I'm not mad about avocado, but I do like guacamole, especially if it is well salted with lots of lime juice and tomato-free. Of course, there are plenty of recipes for it online, but here is my contribution. Try to get the ripest avocados you can, it'll not only taste better, but you'll be making life easier for yourself when it comes to mashing them.
2 ripe avocados
4 spring onions, finely chopped
1 green chilli, deseeded and chopped
juice of one lime
1 clove finely chopped garlic
handful chopped coriander leaves
pinch ground cumin
salt and pepper
Peel and mash the avocados to a consistency you like- I like mine with chunks in, not baby-food smooth. Fold in the rest of the ingredients, bearing in mind to adjust the flavourings, especially the lime and chilli, to your taste.
