When learning recipes from Vita, the amounts are always given as ‘about this much’ rather than exactly. I’ve done my best to get as close as possible below
5 medium sized tomatillos (husks removed)
1 jalapeno (unless you like a lot of spice, then more)
1 half white onion
2-3 garlic cloves
salt and pepper (optional)
Put all ingredients (whole) into a pot and cover with water. Boil for about 10 minutes or until done. Remove items with a slotted spoon into a blender, adding only a bit of the liquid. Blend.
Add more liquid as needed for consistency/texture. Add salt and pepper as desired. Add lime juice and cilantro as desired.
