Stove top

Add to pot:

   - pasta

   - enough water to cover

   - 1 tsp salt

Heat until water boils and then for 8 minutes for most pasta (4 minutes for angel hair). Test for doneness. Drain if desired.

Instant pot

Add to pot:

   - pasta

   - 4 cups water for each pound of pasta

   - 1 tsp salt

Pressure cook. To find the time, divide the "regular" time by 2, rounding down if necessary, then subtract 2. (An 8 minute stove top pasta cooks for 2 minutes in the Instant Pot.)  Natural release for 5 minutes. Stir well. Return lid and let sit for 5-10 more minutes.
