This guide explains how to produce flour from four wild plants: amaranth, acorns, rye grass, and cattails. Each requires specific harvesting and processing steps.
Amaranth
- Harvesting: Collect seed stalks in the fall when the seeds have turned brown and are dry. This typically occurs in late September or early October.
- Drying: Hang the seed stalks upside down in a cool, dry place such as attic rafters. Ensure the area is well-ventilated to prevent mold growth. Allow the seeds to dry completely, which usually takes about 2 weeks.
- Crushing: Once dried, remove the seeds from the stalks and crush them using a mortar and pestle, hand-crank mill, or food processor. Aim for a fine texture similar to commercial flour.
Acorns
- Collecting: Gather fallen acorns in the fall, ideally before they have been on the ground for more than a few days. This ensures freshness and reduces the risk of insect infestation.
- Roasting: Remove the caps from the acorns and score the shells lightly with a knife. Roast the acorns at 250°F (120°C) for 1 hour to kill any insects inside. Allow them to cool before further processing.
- Soaking: Crush the roasted acorns and soak them in water to remove tannins, which cause bitterness. Change the water every few hours until the water remains clear and the acorns taste sweet. This process can take several days.
- Drying and Grinding: Once the acorns are free of tannins, dry them thoroughly in an oven or Dutch oven at low heat (around 150°F or 65°C) for several hours. Grind the dried acorns into flour using a food processor or hand-crank mill.
Rye Grass
- Harvesting: In the fall, when the grass has turned brown and the seeds are mature, cut the stalks and shake them over a basket to collect the seeds. This is typically done in late October or early November.
- Separation: Use wind to separate the seeds from the chaff. Spread the seeds and chaff on a windy day and gently blow or fan the chaff away from the seeds.
- Crushing: Crush the seeds manually or with tools to break them into smaller pieces. This can be done using a mortar and pestle or a hand-crank mill.
Cattails
- Harvesting: In the late summer or early fall, peel and chop the wet roots of the cattail plant. The roots should be harvested when the plant is still green and the flowers are not yet brown.
- Pounding: Pound the chopped roots with water to create a mash. Strain the mash through a fine mesh or cheesecloth to remove any remaining fibers.
- Drying and Grinding: Dry the mash thoroughly in an oven or over a fire. Once dry, grind the mash into flour using a food processor or hand-crank mill.

Baking Notes
Wild flours produce dense, rustic breads. Gluten-free options such as amaranth and rye grass require yeast, honey, or sourdough starters for leavening. Blending multiple sources, such as cattail roots and acorns, can improve nutritional value. Use these flours as partial replacements in recipes.
Storage
Keep the flour in sealed containers in a cool, dark place to prevent spoilage. Use within a few months for best quality.
Common Mistakes
- Not drying the seeds or acorns thoroughly before grinding can lead to mold growth.
- Over-soaking acorns can result in a loss of nutritional value.
- Failing to properly separate seeds from chaff can lead to a gritty texture in the final flour.
Practical Tips
- Start with small batches to refine your technique.
- Experiment with different combinations of flours to find the right texture and flavor.
- Store flour in airtight containers to maintain freshness.
Getting Started
Begin by identifying the plants in your local area. Harvest small quantities to test the process and taste. Gradually increase your harvest as you become more comfortable with the techniques.
