To Preserve Asparagus
Ingredients
Directions
Prepare the asparagus
Wash and dry the asparagus thoroughly, ensuring no sand or earth remains.
Mix dry flour with one‑sixth part crushed salt.
Coat each asparagus stalk with the flour‑salt mixture, focusing on the cut end.
Tie the asparagus into bundles of fifty or fewer, then powder them again with the mixture.
Seal and store
Encase each bundle in a paste made of flour and water, thick as a knife blade.
Ensure there are no cracks in the paste to exclude air.
Place the bundles in earthenware pots and cover with suet or melted fat.
Store in a dry, cool place until needed.

What each ingredient does
- Asparagus
- The vegetable being preserved; it is the main subject of the method.
- Dry flour
- Forms a dry coating and a sealing paste that keeps air out of the bundles.
- Suet or melted fat
- Covers the bundles in the pots, forming a barrier that excludes air.
The step that matters
Ensure there are no cracks in the paste to exclude air. Air reaching the asparagus lets it spoil, so the flour and water paste must be unbroken. Fat cover and airtight sealing work together to exclude oxygen and slow microbial growth.
