When your avocadoes are too hard and won't let themselves be mashed.. chop them into fine dice instead, and fold in a little creme fraiche. Different from both salsa and guacamole, for sure - but very good!
1-2 rather not-very-ripe avocadoes, in small dice
150 g cherry tomatoes, finely chopped
bunch coriander, finely chopped
juice of 1 lemon
1/2 red onion, finely minced
1 garlic clove, finely minced
2 tbsp creme fraiche
