I have made frosting for some birthday cakes before, but this time I want it to be a bit fancier. Try browning the butter, then cooling it to room temperature to give the frosting a nutty flavour.I am up for baking cupcakes for my daughter’s birthday. You can alo use this frosting to fill whoopie pies and you can also colour it with gel food colouring for decorating. There are so many ways to get creative with this frosting. You know this recipe is good because this cream cheese frosting works great in layer cakes without the risk of sliding layers and weeping frosting! cardamom cranberry layer cake with cream cheese frosting.berry chocolate cake with cream cheese frosting.Once you have mastered this thick cream cheese frosting recipe, you will see that it is so thick that you can use it to make layer cakes and for decorating. If you can, buy the cream cheese sold in blocks and make sure to buy full-fat cream cheese, preferably Philadelphia brand. That extra water in the tub product means your cream cheese frosting will be more prone to breaking down or becoming too soft. Cream cheese sold in the tub is formulated to be spreadable and that softer consistency comes the water content: cream cheese sold in the tub has slightly less fat and more water than cream cheese sold in blocks, which is much firmer. The cream cheese product you buy has an impact on this recipe. In fact, you end up with a frosting that tastes a lot like cheesecake, tangy and not overly sweet! Cream cheese in the tub versus blocks of cream cheese The cream cheese remains intact, and no water leeches out.īy following this mixing order, you can make a frosting with significantly less sugar. The sugar is coated with fat, therefore making it more difficult to draw out the moisture from the cream cheese. Step 2: Once the butter and icing sugar are well mixed, THEN you add in the cream cheese.Step 1: Cream the butter with the icing sugar first, thereby coating all the little sugar molecules with fat. ![]() Without resorting to adding an excess amount of icing sugar, to make a thicker cream cheese frosting that can be used to frost a cake or decorate cupcakes, the solution is simple: change the order you mix your ingredients in: How to make thick cream cheese frosting that is stable and can be piped ![]() This leads to a cloyingly sweet cream cheese frosting that doesn't taste very good. Bakers tend to overload the frosting with powdered sugar to stiffen the frosting. The frosting doesn't hold its shape when piped and it's quite unstable. Without all the extra powdered sugar, the frosting is too soft to work with. This is the main reason why most cream cheese frosting recipes recommend a huge amount of icing sugar. But since cream cheese contributes double the moisture, when the icing sugar draws out that moisture, you end up with a soupy, runny, unstable cream cheese frosting. Butter has very little moisture to draw out, so you can make a thick, pipeable frosting with butter and icing sugar without much worry. When the cream cheese is creamed with the butter, and then the icing sugar is added in, the icing sugar draws out that moisture from the butter and the cheese. What remains in both cases is mostly water, so cream cheese contains more moisture than butter. Remember that most grocery store butters have roughly 80 % fat in them, while cream cheese is half of that, around 40 % fat. Why is it so unstable?Ī block of cream cheese contains a lot more water than the same weight of butter. The reason cream cheese frosting recipes call for so much powdered sugar is because without the extra powdered sugar, cream cheese frosting tends to be runny, unstable, weepy, and soupy. Typical recipes for cream cheese frosting have you cream the butter and the cream cheese together, then add A TON of icing sugar. Why is cream cheese frosting runny or too sweet?

This means the outlet isn’t connected to other outlets or things that might use some of the electricity coming from the power source (box). What’s that? A dedicated circuit or line or outlet is one that only goes to one place/outlet from the electric box. Also, because the pump uses a lot of power, the outlet that you plug the extension cord into should be on what is called a “dedicated circuit”. So, if the wire in the extension cord is too thin then the cord can eventually burn up or overheat causing the pump not to run. You want a thicker extension cord, because a pool pump requires a good amount of electricity to run. You really want a #10 gauge, but these cords are pricey. If this is the case for you, then use an extension cord that has at least a #12 gauge wire. Many only use an extension cord as theymay not have the money to do it right. I recommend only using an extension cord temporarily until you can have a permanent power line buried that runs to the pump. So due to these pumps having standard cords on them, the easiest way to get power to your pool is to use an extension cord connected to some outlet from the house. Since pumps for above grounds only come as 120V, they all have standard three-prong plug cords attached to them. The two big differences are above ground pumps cannot draw water upward and that above ground pumps come only in 120V (volt) as they are not what is called “dual voltage”. I say this because pumps for in-ground pools are a little different. Whatever It TakesĪbove ground swimming pools come with above ground pool pumps. And if you are going to get a pool, you’ll need electricity. If I hadn’t seen it for myself, I wouldn’t believe it. ![]() It’s almost unbelievable to think that there were homes as recent as the eighties in Florida that had no electricity. Sounds crazy, huh?įor a few years after that and whenever I was way out in the boonies, I would pay attention to power lines and how they wouldn’t always reach all the homes. In the eighties, electricity only came from overhead power lines and during the drive back I noticed that there were no lines going to some of the other houses and realized that my customer wasn’t the only one without electricity. It was only a 15’ round pool so we built it pretty quickly complete with its pump and filter pack and the pump’s cord that had nothing to plug into and we were soon on our way back to Orlando. After I explained it to him, he of course wanted me to install the pool anyway and said that he would just have to figure it out later. He had no idea that a pool has to have a pump and filter. He didn’t know what I was talking about as he just went to Rec Warehouse in Orlando and bought a swimming pool. “Pump and filter?” my salt-of-the-earth customer asked. When I arrived, I was still unaware that they had no electricity and started asking the standard questions of where did they want the pool and where did they want the pump and filter. As you can imagine, this place was way out in the middle of nothing. And it was always the last house on the right. It seemed to me that I was always building pools way out in the boonies. ![]() I had the best map you could buy and it still didn’t have all the streets on it, but I was good at finding places. Using just a map, I drove way out to the other side of Lake County to a small house that looked like a shack.

One note of caution: The errors of a and b will generally be correlated, which makes them unnecessarily big. ![]() Assuming that the confidence intervals are symmetrically spaced around the fitted values (which in my experience is true in all reasonable cases), you can use the following code: cf_coeff = coeffvalues(cf) Ī_uncert = (cf_confint(2,1) - cf_confint(1,1))/2 ī_uncert = (cf_confint(2,2) - cf_confint(1,2))/2 ![]() You can access the fit results with the methods coeffvaluesand confint. The option 'poly1' tells the fit function to perform a linear fit. Note: x and y have to be column vectors for this example to work. ![]() It does not indicate that the observed value is somehow better than expected, since the best possible outcome for percentage error is that the observed and true values are equal, resulting in a percentage error of 0.If you have the curve fitting toolbox installed, you can use fit to determine the uncertainty of the slope a and the y-intersect b of a linear fit. Thus, in the context of an experiment, a negative percentage error just means that the measured value is smaller than expected. If the observed value is larger than the true value, the percentage error will be positive. For example, given an observed value of 7, a true value of 9, and allowing for a negative percentage, the percentage error is: v observed – v trueĪ negative percentage error simply means that the observed value is smaller than the true value. This occurs if we do not take the absolute value of the error, the observed value is smaller than the true value, and the true value is positive. However, it is possible to have a negative percentage error. In most cases, only the error is important, and not the direction of the error. Negative percentage errorīased on the formula above, when the true value is positive, percentage error is always positive due to the absolute value. Please refer to the standard deviation calculator for further details. True values are often unknown, and under these situations, standard deviation is one way to represent the error. The equations above are based on the assumption that true values are known. Absolute error = |V observed – V true|įor example, if the observed value is 56.891 and the true value is 62.327, the percentage error is: |56.891 – 62.327| Refer to the equations below for clarification. The absolute error is then divided by the true value, resulting in the relative error, which is multiplied by 100 to obtain the percentage error. The computation of percentage error involves the use of the absolute error, which is simply the difference between the observed and the true value. If, for example, the measured value varies from the expected value by 90%, there is likely an error, or the method of measurement may not be accurate. In most cases, a small percentage error is desirable, while a large percentage error may indicate an error or that an experiment or measurement technique may need to be re-evaluated. A small percentage error means that the observed and true value are close while a large percentage error indicates that the observed and true value vary greatly. Calculating the percentage error provides a means to quantify the degree by which a measured value varies relative to the true value. Error can arise due to many different reasons that are often related to human error, but can also be due to estimations and limitations of devices used in measurement. When measuring data, whether it be the density of some material, standard acceleration due to gravity of a falling object, or something else entirely, the measured value often varies from the true value. known values as well as to assess whether the measurements taken are valid. It is typically used to compare measured vs. Percentage error is a measurement of the discrepancy between an observed (measured) and a true (expected, accepted, known etc.) value.
