Wash your meat and pat dry. Fill a deep vessel with water and heat this until the water has reached a simmer. Then add in the salt and sugar and let them dissolve while the water reaches a boil.
Take this off the heat and let the brine liquid cool to room temperature. Then, transfer to a container big enough to hold your meat, making sure you have the lid handy as well.
Place your meat in and refrigerate for 6 hours. Then, discard the brine, wash and dry your meat. There, it's brined and ready to cook further.
