Welcome to the forum. I think you will be able to get a good deal of information about sauce and sauce making, if that is what you are desiring to know. While some posters feel they must carry an air of secrecy, whether justified or not(such as either professional sauce makers or just plain paranoid), you will find at least most willing to point you in a general direction, if not an outright complete sharing of knowledge. In general, as with anything "homemade," the possibility does exist for something waaaaay better than off the shelf. There are however some really GREAT specialty sauce makers as well, that are represented here on the forum.
Here is an apple BBQ one that I truly LOVE. I got the base awhile back off a Steve Raichlen book recipe, and tweaked it to the below directions. It tastes best on pork, of any type. Best made a couple of days ahead, to let flavors meld. It has an UNMISTAKABLE apple flavor. I particulary like this drizzled over a sausage sandwich. :thumb:
SPICY APPLE BBQ SAUCE
1 cup ketchup
2 cups apple juice
1/3 cup molasses
1/4 cup cider vinegar
1/4 cup firmly packed dark brown sugar
2 tablespoons granulated sugar
1-1/2 teaspoons chile powder
1/2 teaspoon celery seed
1-1/4 teaspoons ground cinnamon
1/2 teaspoon ground cloves
Coarse salt (kosher or sea) and freshly ground black pepper
** In addition, I now add 2 tbs. of ancho chili powder.
As I think this give this a nice smokey background.
Also I add onion powder 1/2 to 1 tsp, and cayenne in same amount for more kick.
Place the ketchup, apple juice, molasses, vinegar, brown and granulated sugar, chile powder, celery seed, cinnamon, and cloves in a large heavy saucepan and gradually bring to a boil over medium heat, whisking to mix.
Reduce the heat to low and simmer the sauce until thick and richly flavored, about 40 minutes, whisking often. Correct the seasoning, adding salt and pepper to taste. The sauce should be highly seasoned.
