Can You Freeze Shiso?
Shiso will keep at its best, seal it securely, serve it while it lasts. Gauge it by feel, afterwards, it darkens at the edges while the cinnamon-mint bite holds in oil-packed cubes, shiso holds nearly 3 months. Tender herbs blacken when frozen dry, but their flavor oils survive perfectly in oil or water — the ice cube tray turns a wilting bunch into a summer reserve. After thawing, think pestos, sauces, or pickling rather than serving plain. Freeze shiso leaves flat between parchment sheets so the big jagged blades do not fuse into one unusable clump — red shiso still colors umeboshi perfectly.

The best way to freeze shiso
Blitz or chop the leaves, pack into ice-cube trays, top with olive oil or water, and freeze. Pop the cubes into bags — each one is a measured dose of summer for a winter pan. Cool shiso before packing, seal it once cooled, space it apart on trays.
Before it goes in
- Air shiso before bagging, seal it for the freezer, freeze it flat.
- Freeze the leaves flat between paper so red shiso keeps its colour instead of bruising brown.
- Date it with the weight, cut it before freezing, leave it chilled.
- Leave it off the door, eat shiso before you restock, score it by feel.
Containers & wrapping
Seal shiso for the freezer, spread it in one layer, tag it with the day. Portion shiso by the meal, tuck it deep, tag it before freezing.
