One of the most important functions of eggs is to provide structure and determine texture. We saw this with breads, cakes, cookies, and muffins, with brownies, and also with meringue. But there’s one more category of baked good that depends on eggs: custards and creams. Eggs set and thicken crème brûlée, quiche, cheesecake, pastry cream, and crème anglaise. In this post, we’ll first review how an egg cooks, then explore how different ingredients and techniques affect this process to create smooth custards and creams.
These buns are a twist on the classic Chinese egg custard buns (奶黃包, nǎihuángbāo). They still have the creamy custard and the fluffy steamed bun, but I added pumpkin and fall spices to both the filling and the dough to create a pumpkin spice version. Notes on ingredient substitutions and the science behind the custard filling, dough, and steaming process follow the recipe!
Red bean soup (紅豆湯,) is a popular dessert throughout China, Taiwan, and Hong Kong. It’s made from red beans (紅豆, also called adzuki beans) which are incorporated into many East Asian desserts. Red bean soup itself is versatile. It can be eaten hot or cold, plain or with toppings, liquid or frozen. When my mom first dictated her version to me, she cautioned, “糖最後加，不然紅豆煮不爛！Don’t add the sugar until the end, else the beans will never soften!” Today, I’m sharing my mom’s recipe, adapted for a typical Western kitchen and pantry, then discussing the science behind her words.
In the last post, we discussed how sugar preserves the structure of cooked fruit. This comes in handy for fruit pie fillings, which often become a mushy and wet (but nevertheless delicious) mess. In this recipe, apples are tossed with sugar and drained. The drained liquid is cooked into a thick syrup that’s added back to the apples and baked. The apples maintain some crunch, not much water leaks into the pie, and the syrup adds an extra punch of flavor. Let’s take a look at the recipe and then discuss the science!
Over the last few posts, we discussed a lot of sugar’s roles in baked goods. It’s important for flavor, texture, structure, and color in cookies, cakes, and muffins. But sugar’s roles in baking extend further. Sugar is important in meringues as a stabilizer, in yeast breads as a source of energy for the microorganisms, and in fruit desserts to preserve the structure and texture of the fruit. In this post, we’ll explore sugar’s myriad roles in these sweets.
