Acorn Flour

part of: Oak

Acorn flour is a gluten-free flour milled from the nuts of oak trees. It has a mild, earthy flavour with a subtle sweetness and a slightly gritty texture that varies depending on how finely it’s ground. The full-fat version retains the natural oils of the acorn, giving it a richer taste but shorter shelf life.

Historically a staple food for Indigenous peoples across North America, Europe, and East Asia, acorn flour has found a small but devoted following among foragers and alternative baking enthusiasts. It can be used in pancakes, flatbreads, pasta, and as a thickener for soups and sauces.

It’s not widely available commercially in Australia but can be made at home from foraged acorns with patience and the right species of oak.

How it's made

Acorns are harvested from oak trees, shelled, and soaked or rinsed repeatedly in water to leach out the bitter tannins. Once the bitterness is removed, the acorn meat is dried thoroughly — either in the sun, a low oven, or a dehydrator — and then ground into a fine flour using a mill or food processor.
