Here's a new ingredient for me: chia seed. It's very nutritious, contains calcium (bonus!), and is a natural thickener. I decided to mix some into my pancake recipe to thicken the liquid ingredients in place of yogurt or buttermilk.
The recipe I used was King Arthur Flour's Homemade Whole Grain Pancake Mix. Instead of a cup of buttermilk or half yogurt / half milk, I used a cup of whatever non-dairy milk was open at the time (probably coconut... not the canned kind) plus a teaspoon of ground chia seed. The pancakes came out nice and fluffy – perfectly fine without dairy. I might add a teaspoon of lemon juice next time to get some of that cultured-milk tang.
