Here's a tip from issue #10 of Put a Egg On It. Cure egg yolks for two days in soy sauce for a custardy addition to oatmeal! This requires no skill except for cracking open an egg and separating the white from the yolk.
Here I have a bowl of overnight oats with a cured yolk, chopped flowering mustard greens, garlic scapes, and sliced turnip. Sure beats a bowl of sugary oatmeal from a packet!
