My recipe for guacamole is fairly simple:
1 mashed ripe avacado 2 tsp Greek yoghurt 1 tsp lime juice 1 1/4 cup chopped cherry tomatoes 1/2 tsp ground cumin salt and pepper to taste.Apart from the cumin, I think my recipe is pretty basic but I note that others use cilantro, hot peppers or salsa, lemon instead of lime and even "Miracle Whip" instead of yoghurt (tho' that comes from a Kraft recipe).
I suppose it's a matter of to each their own but I'd be interested to know other's preferences.
