Chuck the tomatoes into a bowl of boiling water for about a minute (any longer and the tomatoes will go mushy)

Skin the tomatoes and chop to desired size

Peel the avocados and chop. Throw everything into a bowl together

Crush the garlic into the bowl

Squeeze in the lemon juice

Add Tabasco according to taste

Throw in the fresh coriander and mash everything. If you mash too long, it will become more of a paste. Chunky is better
