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.
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.
You know when recipes indicate a specific size of egg? They’re not just trying to mess with you. In fact, 1 cup of eggs can be made with 4 jumbo, 4 to 5 extra-large, 5 large, 5 to 6 medium or 7 small eggs, so it is good not to use the sizes interchangeably. The good news is that large eggs are fairly standard in U.S. recipes, thus they’re your best bet to keep around if you don’t wish to buy multiple sizes.
Who besides me is crazy enough to keep self-rising flour in the pantry? Honestly, there’s no need to since you can make your own at home. For each cup of flour, add 1 1/2 teaspoons baking powder and a 1/2 teaspoon salt; mix extra and store it in an airtight container for months. Now go forth and bake some 1-2-3-4 cake!
