If the gravy looks too red, your chili powder may be a hot type. Use Kashmiri or deggi mirch for color with less heat.
Vegan: tofu instead of paneer; cashew or coconut cream instead of dairy cream.
Make-ahead: prepare gravy through the blend step, freeze flat, thaw and finish with fresh vegetables.
Store leftovers in an airtight container in the fridge up to 3 days; reheat gently with a splash of water.
