Does your grocery store have the nerve to inconsistently stock cake flour? Does it drive you crazy to see recipe after recipe that calls for it, and wonder what else you can use? Good news: Cake flour is really easy to make at home. Add two tablespoons of corn starch to each cup of regular flour and sift this mixture together twice. Measure your cups of flour from this mixture.

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.

The biggest different between all-purpose and bread flour is the amount of gluten: bread flour has more of it. But it may seem annoying to have to keep a giant bag of bread flour around if you’re only an occasional bread-baker. Enter a product known as a “gluten additive” or gluten flour, something you can usually add one tablespoon of to each cup of all-purpose flour to turn it into bread flour. Think of all the cabinet space you’ll save!

Have a lot of egg whites or yolks leftover from a recipe but don’t know how many? A good approximation to keep in mind is that 1 large egg yields about 1 tablespoon of yolk plus 2 tablespoons of white. This has come particularly in handy when I have halved a recipe that called for an odd number of eggs — I simply beat one egg and measured out 1.5 tablespoons.

In perhaps my most persnickety tip yet, did you know that when a recipe calls for a drop, pinch or dash of an ingredient, this can be translated into an actual measurement? 60 drops yields one teaspoon, 1 dash is equal to 1/16 of a teaspoon and 1 pinch is 1/8 of a teaspoon. Now, try to get your head around the fact that someone, somewhere actually took the time to measure these things out.

Cream is labeled illogically, with names and not numbers representing milk fat within. This ought to help sort them out: half-and-half (equal parts milk and cream) has 10.5 to 18 percent milk fat; light cream (a.k.a. table cream) ranges from 18 to 30 percent, but is most often actually 20 percent; whipping cream (a.k.a. light whipping cream) has 30 to 36 percent; and heavy cream (ironically, better for whipped cream than “whipping” cream, though both work) has 36 to 40 percent. Double cream (not widely available in the U.S.) has 42 percent. Oh, and it is awesome.
