Perfectly ripe avocados are the key. I always add chilli and a dash of tabasco sauce for extra bite. Take a ripe avocado, some lemon juice, 8oz curd cheese, 2 garlic cloves, hot pepper sauce, and a tablespoon of lime juice. Peel avocado, discard stone, reserve and dip in lemon juice. Mash flesh with curd cheese until smooth. Season and stir in garlic, pepper sauce and lime juice. Cover and put in fridge if you don't eat it immediately.
My favourite Guacamole is made with;
1 ripe advacado mashed with a fork, juice of 1 lime, finely chopped spring onions, fresh coriander, and finely chopped fresh chilli, with or without seeds, and sometimes chopped vine tomatoes
My girlfriend is Mexican and she has tought me the best way...any other way pales in comparison...especially that ready made in a jar or tub rubbish that you get in supermarkets, that stuff is vile!! Ripe avocados obviously, better to be slightly under than over...remove ALL blackened or bruised bits as this discolours the guacamole quickly if left for any period of time. Don't mash it, use a knife to kind of chop/mash it, then finely chop some onion (equal amount of onion to avocado) and mix in (do not mash) one or two finely chopped chillis (depending on strength) then fresh lemon/lime juice and salt (sea salt) The lemon/lime juice adds acidity and stops oxidisation and the salt counters the acidity, don't add too much or the guacamole will go runny. Do NOT add tomatos, do NOT add coriander, do NOT add garlic and DO NOT mash it up! The texture should be fairly lumpy.
