I recently cooked the fool-proof Instant Pot electric pressure cooker Butter Chicken curry I've done a number of times. When I came to add the spices I found the missis had helpfully stolen the turmeric and cumin jars to make sure they fit the new spice rack we're putting in the new house. I pressed on, unperturbed- it's just a teaspoon of each, how bad can it be if they're missing?
Answer: bad.
Even just missing those 2 spices made a huge difference. I tried rescuing a little by adding a good tablespoon of some Nam Pla Prik I had in the fridge (heresy and know, mixing Thai and Indian) and while it added good heat, it was in vain. I ate the lot of course, but grudgingly to say the least.
We are in the new house now and converting a downstairs bathroom into a walk in pantry so will be fully up and running spice-wise in the next week or so and making my first batch of Taz base in the frozen north of Illinois (where we are getting 7" snow overnight).
