When I saw the opportunity to review Cooking with Whey, I jumped at it. I am already a big fan of author Claudia Lucero from her book Instant Pot Cheese. However, I have always been a little bit frustrated at the amount of whey that I produced as a by-product of the simple cheeses that make. Lucero and other cheesemakers always say that one should save the whey for other uses.
I dutifully strained and save the whey each time. However, the advice on the Internet seemed to repeat the same list on every site, recommending that I add it to smoothies, pour it into my compost or feed it to my chickens.
I refuse to buy chickens just to use up my whey.
Lucero's new release, Cooking With Whey, changes everything. The book is full of practical advice for using whey in the kitchen as a matter of course, as a rich addition or as a substitution for milk and other dairy products. After glancing through the cookbook, I found myself making cheese simply to have a fresh batch of whey to experiment with! Luckily, one can never have too much cheese.
The book starts with a very clear explanation of the different types of whey and how these types can be used in the kitchen. I had seen, of course, that the whey from making ricotta with lemon juice was very different than the whey from my thickened yogurt, for example, but I had not understood how to deal with this. Lucero explains clearly how we can use these different types of whey as substitutions for vinegar, milk and broth in our own everyday cooking.
Cooking With Whey is described as a Cheesemaker's Guide to Using Whey, which makes it hard to understand why there are reviews from people who do not make cheese or who have gone out to buy whey in order to make the recipes. Although it is at heart a cookbook, Lucero also describes many household options without once expecting me to have a chicken coop (although there are two recipes for dog treats) and another two chapters to use the whey in drinks, including instructions on how to ferment and/or distil the whey to make your own alcohol. The non-culinary uses alone will ensure that I never again throw away the whey.
However, if you are not already a convert to home-based cheese making, don't worry, because Lucero starts with basic instructions and simple recipes to create all three types of whey in your own home without having to make a major investment. This means that the book is standalone and does not require the reader to find a source of whey in order to get started.
The recipes are not sorted by whey type, as most recipes will allow for multiple options. However, each recipe has a list of the types of whey that could be used with it, ranked in a simple system of BEST, GOOD and OKAY. For recipes that require a specific whey (for example, acid whey for fermenting for a specific type of bread) then the notes reinforce this to ensure you don't end up with a flat loaf.
My favourite cheese leaves me with sweet whey, so I skipped past the practical uses (pets, gardening, bath softener) and went straight to the cocktail section.
Unfortunately, the recipes are given in imperial format only, which makes this book slightly harder to follow for non-American. The cocktails list all ingredients in ounces (I presume fluid ounces rather than by weight!). Still, it was relatively easy to see the proportions and take a guess. I was exciting to discover that whey adds texture to drinks in the same way that egg whites and aquafaba do.
I immediately set out to make the Brazilian Limeade and was already won-over by the thirst-quenching, frothy result. But then I added rum to make the Lightweight Caipirinha which makes for a fantastic long drink on a warm evening.
Whether you want to learn to swap whey for other ingredients or find ways of using it up outside of the kitchen, Cooking With Whey has you covered. This is a must-have resource for anyone who has guiltily poured a liter of whey down the sink, which recipes that will inspire you to generate even more whey just so that you can cook with it.
