Cupboard or fridge

Keep eggplant dry until ready to use. They can be kept in the fridge loose in the crisper, or a cool dry cupboard for maximum freshness. Wrap cut eggplant in a beeswax wrapper or use a silicone food saver over the cut end. Ethylene sensitive: keep away from foods that release ethylene so they don’t ripen too quickly.

Blanch for 2-3 minutes. Cool in ice water. Flash freeze in a single layer on a baking paper lined tray so they don’t stick together, then transfer to an airtight container / zip lock bag in your freezer. Alternatively, eggplant puree or roasted eggplant can be frozen. Add frozen eggplant straight to your cooking
