Spice Paste Storage: Fridge or Pantry?

The Golden Rule

Unopened, commercially sealed spice pastes can stay in the pantry. Once opened, almost all spice pastes need refrigeration.

Paste-by-Paste Guide

• Curry paste (Thai): Fridge after opening. Lasts 1 month. Press plastic wrap onto surface to prevent oxidation.
• Harissa: Fridge after opening. The olive oil layer on top helps preserve it. Lasts 2-3 months.
• Gochujang: Fridge after opening. Lasts up to 2 years due to fermentation. May darken over time — normal.
• Tomato paste: Fridge. Freeze leftover portions in ice cube trays for easy use.
• Tamarind paste: Pantry OR fridge. High acidity acts as natural preservative. Lasts 6+ months either way.

Signs of Spoilage

Discard if you see mold, off-smells, or color changes. A thin layer of oil separating is normal — just stir it back in.

Pro Tip

Transfer pastes to smaller containers to minimize air exposure. A half-empty jar of curry paste oxidizes faster than a full one.
