tips from the smitten kitchen

Once again, it is not you but your baking powder sabotaging your awesome kitchen prowess. That slightly bitter, kinda “tinny” flavor you often experience when biting into a muffin, biscuit or scone is the result of using a baking powder in high quantities — as is needed for these quick-rise treats — with aluminum in it. Fortunately, aluminum-free brands such as Rumford or Bob’s Red Mill are easy to find, and are no more expensive. Or, you can just go rogue and make your own.

I can’t tell you how many times I have burnt fried chicken or overcooked a caramel and not realized that my candy/deep fry thermometer was to blame. If only I had absorbed enough sixth grade science class to remember how ridiculously easy it is to check to see if had been accurate from the get-go! Simply place your candy/deep fry thermometer in a small pot of water and crank up the heat; the temperature should read 212°F (100°C) as it begins to boil. If yours does not, you can either take into account the few degrees it may run hot or cold when you cook, or return it.

Using a round whisk for a squared-off pot drives me crazy, especially when I find unmixed custard, pudding or sauce bits in a channel along the bottom edge. Whisks such as this or this or this or this are painless investments, and come in handy when you want a perfectly-mixed chocolate pudding, and you want it now.

So you’ve made some fruit scones or peach cupcakes and you notice that the end product is streaked blue and green. Sound familiar? In almost every case, it’s not you, it’s your baking powder. Baking powder with aluminum in it reacts to acidic ingredients, causing this discoloration and what many people find to be a “tinny” or metallic taste. Fortunately, this is as easy to rectify as ditching your baking powder for an aluminum-free brand, such as Rumford (the brand also makes Clabber Girl baking powder, which, oddly, does contain aluminum) or Bob’s Red Mill.

I hope you’re sitting down for this. Depending on how you measure a cup of flour, you might end up with as little as 4 ounces and as much as 7 ounces in it, a terrifying thought when using a recipe that demands accuracy. The generally accepted measuring method–and the one you should use for the funny reason that it is the one that the person who wrote your recipe used–is to lightly fluff a canister of flour with a spoon, then scoop the flour into your cup until it is over the top and level it with something flat, trying your very best not to compress it in any way. The most accurate way to measure flour, however, is to weigh it, so if you have a recipe that includes a weight, consider it a plus.

Is there any difference between parchment and waxed paper? Briefly, yes: Parchment has been coated with silicon so it can be used at high temperatures and virtually eliminates the need for greasing a pan. Waxed paper will smoke at high temperatures — and the wax will come off in your food — and is therefore less versatile. I do not recommend swapping the two when lining a cake or roasting pan.
