Frequently Asked Questions

Q

What ingredients are in Thai red curry paste?

Traditional Thai red curry paste contains dried red chilies, lemongrass, galangal, shallots, garlic, cilantro roots, shrimp paste, and toasted cumin and coriander seeds. A 1-cup batch uses about 200g of ingredients total. The paste keeps 2–4 weeks refrigerated or 6 months frozen.

  • Dried red chilies: 30g (the base and color)
  • Lemongrass: 45g (aromatic backbone)
  • Galangal: 20g (earthy heat, different from ginger)
  • Shallots: 40g (sweetness)
  • Garlic: 25g
  • Cilantro roots: 15g (stems work as substitute)
  • Shrimp paste: 10g (umami depth)
  • Cumin + coriander seeds: 15g (toasted and ground)
Q

How much curry paste do I need per serving?

Most curry recipes use 2–4 tablespoons of paste per serving. One cup of homemade paste makes 4 servings of curry (4 tbsp each). For a family of four, one cup is enough for one meal. Commercial pastes are more concentrated, so you typically need less.

  • Standard serving: 3–4 tablespoons per person
  • 1 cup paste = 4 servings of curry
  • Freeze in 4-tablespoon portions for convenience
  • Homemade paste is less concentrated than commercial brands
  • Adjust to taste — start with 2 tbsp and add more
Q

How long does homemade curry paste last?

Homemade curry paste keeps 2–4 weeks in the fridge and 4–6 months in the freezer. Thai pastes with shrimp paste and chilies last longer due to natural preservatives. Indian pastes with yogurt or tomato (like tikka masala) have shorter fridge life (2 weeks). Freeze in ice cube trays for easy portioning.

  • Fridge: 2–4 weeks in airtight container
  • Freezer: 4–6 months (Thai pastes)
  • Freezer: 3–4 months (Indian pastes with dairy)
  • Ice cube trays: perfect for 2-tablespoon portions
  • Japanese curry roux: 1–2 weeks fridge, 3 months frozen
Q

Is homemade curry paste cheaper than store-bought?

Yes. Homemade curry paste costs roughly $0.50–$0.75 per serving compared to $1.50–$3.00 for premium brands. A 1-cup batch of Thai red curry paste costs about $3.00 in ingredients and makes 4 servings ($0.75/serving). Store-bought premium paste runs $5–8 for the same amount.

  • Homemade Thai red: ~$3.00 per cup (4 servings)
  • Store-bought premium: $5–8 per jar (4 servings)
  • Savings: 50–70% less than premium brands
  • Bulk spices reduce cost further (buy whole, toast, grind)
  • Japanese curry roux: even cheaper at ~$0.30/serving homemade
