Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starch that softens and turns fluffy when boiled and mashed.
- Milk
- Adds moisture and richness to the mash, making it smoother and softer.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel in the mash.
The step that matters
Boil for about 29 minutes, checking for doneness with a fork.. Potatoes must be fully tender throughout before draining; undercooked centers stay firm and grainy when mashed, while overcooking makes them waterlogged.
