Ingredients
For a basic starting point:
120ml white wine vinegar
2 tsp salt
2 tsp sugar
1 tsp black pepper
2 crushed garlic cloves
120 ml Olive Oil
Additional options:
1 tsp onion powder
1 tsp mustard powder
Depending on the meat/fish:
Chopped herbs: Sage, Rosemary, Thyme, Lemon juice and zest, garlic powder
Ground Spices: Chilli, cumin, ginger
or whatever you fancy
Method
Mix all the ingredients well except the oil then beat it in slowly to emulsify it.
Cover the meat/fish with the emulsion and leave for an appropriate time.
Approximate Timings - Hours
Note that marinating for too long will make the meat seem soft (the acid is partly cooking it)
