This recipe-manifesto considers the political theology of milk as perfecting a relation: between mother and child, between sovereign state and lawful citizen, and between corporation and consumer. Insisting on the importance of milk as inherently relational, I suggest that instead of swapping dairy for plant milk at the grocery store, or considering plant milk as superior to dairy, making plant milk the DIY (do it yourself) way offers a method of ethical relations, care, and resistance. An oat milk recipe is provided, including simple and straightforward instructions. The slowness of making milk, the essay suggests, allows us to value the labor we put into milk. It further forces us to reflect on the reasons why we need it and want it, including a more careful consideration of which relations we want to foster through milk and which relations we must, or want to, resist.
