It’s so easy to make stock but super easy in insta pot. 30 minutes on high pressure and let it naturally release. I use onion, carrot, celery, cilantro stems, mushrooms , broccoli stems. Adding a piece of ginger will be good but i forgot.
What to use stock for? You can use to cook rice ,quinoa, millet or in soup. I like to use for soup in winter time and soups are good for work lunch. Easy to eat and carry. You can also use to make roti, paratha dough when you are adding veggies or spices. Am not sure how plain roti dough using stock will turn out. But won’t hurt to try. It will add nutrition.
