Red oak
Quercus rubra
Higher-tannin acorns typically need more leaching than white oak. Still a potential starch, more work. Identify oak group by acorn cups and leaf lobes (bristle tips on red oak group).
GROW → HARVEST → EAT → DRY → POWDER → CAPSULE → GUMMY — forms are not equivalent. Food first.

Edible portions
- acorns after thorough leaching
Absence of a portion from this list means it is not treated as food here — not that every other part is toxic.
Growing
- Climate. 3–8
- Light. Full sun
- Soil. Average
- Planting. Large tree.
- Harvest. Fall. Leach longer than white oak as a rule of thumb.
Processing, drying, storage
- Processing. More tannin generally = more leaching.
Preparation and culinary uses
- Leached flour
