@2afdf712 willow oaks, I wait for a hurricane or tropical storm to blow them all down. Live oaks, I go for a walk around the neighborhood and pick off ripe ones on low hanging branches. 

Prolonged heat turns acorns and acorn flour bitter. I don’t heat/cook acorns more than 2-3 minutes. That’s why those pancakes are so small. I mostly make pastes, noodles, dumplings, dips, powders for dusting, etc.
