So my favourite marinade recipe goes like this... It's pretty simple.
About one and a half glasses red wine (I prefer Shiraz)
A few tablespoons of honey
Two or three big glugs of soy sauce (the dark and sticky type)
2 Tots brandy, 2 teaspoons brown/palm sugar, A bit of olive oil, black pepper and salt. Herbs that match the meat you are marinading, ie thyme or originum for red meat, rosemary and sage for lamb/mutton, etc
Mix all up, taste it to see if you are happy with the flavour, and soak your chosen meat in there!
Enjoy my pretties, I did!
