How to substitute silk, step by step
- 1
Pick the right substitute for the job
For most recipes use Cupro (regenerated cotton linter) — linings and slip dresses. If you need a different texture, Bamboo lyocell works for bedding and scarves.

Measure using the correct ratio
N/A. Weigh rather than eyeball it — small errors show up much faster when replacing silk.

Taste and correct
Plant swaps are usually a little less salty and less rich than silk. Season at the end and add acid (lemon, vinegar) or umami (miso, nutritional yeast) if the dish tastes flat.
Mistakes to avoid
- Swapping by volume when the recipe measures silk by weight — check the ratio above first.
- Using a sweetened or flavoured version in a savoury recipe.
- Ignoring the method change: Cupro is the closest hand-feel to silk and washes far better.
- Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.
