Recipe Questions

How spicy is Japanese curry in this dish?

Japanese curry powder offers mild warmth rather than intense heat, so the soup is pleasantly aromatic not fiery. Adjust curry powder to taste for extra heat.

Can I make this gluten-free?

Absolutely. Substitute soy sauce with tamari and use gluten-free curry powder or roux to ensure the dish fits gluten-free diets.

What lentils work best?

Brown or green lentils hold their shape well after simmering, providing hearty texture and absorbing the curry flavors beautifully.

How can I add richness?

Stir in a splash of coconut milk at the end, or top each bowl with crispy fried onions before serving for extra depth.

Are there other vegetable options?

Feel free to swap regular potatoes for sweet potatoes to add subtle sweetness, or use seasonal vegetables for variety.

Is this suitable for vegans?

Yes. Choose vegan-friendly curry powder and miso, plus plant-based broth and garnishes for a wholesome plant-based meal.
