Reduce the sugar in sauce recipes. Venison's natural flavor is sweeter than other meat, therefore, sauces developed for beef may be too sweet.
Use mild vegetable acid to tenderize. Vinegar, tomato sauce, and some French dressing sauces are good for tenderizing. Cover the meat with the marinating sauces. Only marinade in the refrigerator for a maximum of 24 hours. After marinating longer than 24 hours, the meats tends to get mushy.
