I love spicy food, though can’t eat it anymore for health reasons 😞. I’m not sure why your DH does this @Humpfree.
If he’s wanting to up his chilli game, in terms of eating it, he needs to start small, so cheese on toast topped with paprika, or cooking a curry using 1 small chilli (Birds Eye).
But we always ate spicy, hot food even as young children (Punjabi), and in a biryani, I will do 1kg meat and rice, potatoes and put 20 Birds Eye chilli in, but then we eat very, very spicy food.
I tend to use half a scotch bonnet per kg of meat for stuff like jerk chicken.
Could you suggest to DH to start small, like the cheese on toast and allow you both to become more used to the heat?
As an aside, vindaloo pre-made from the supermarket isn’t spicy.
Could you make lassi (yogurt drink) to go with it? And always have rice and salad.
If the food is too spicy, mix small amounts with rice to dampen the heat, have salad made from watery veggies like cucumber and drink the lassi.
Would you be amenable to turning the potatoes into another couple of meals, such as using a couple of them in a stew, or in a savoury mince?
