1
Infuse the sauce: Combine the tomato puree, onion, garlic, hot pepper flake, ancho, chipotle, celery seeds and salt in a large, nonreactive saucepan.
-
2
Bring to a boil, then reduce heat and simmer until all the vegetables and dry chiles are soft, about 30 minutes.
-
3
Prepare the jars and lids: Wash all jars and lids thoroughly with soap and water and rinse well.
-
4
Fill your canner with enough water to cover the jars by at least 1 inch and bring to a simmer.
-
5
Using a pair of canning tongs, lower the jars in gently, tilting them to fill with the hot water.
-
6
In a small saucepan, keep some water warm but not boiling; place the lids in the water.
-
7
Have an additional kettle of water on to boil.
-
8
Strain the sauce: Ladle the sauce into a fine-mesh sieve over a large bowl or other container, pressing with the back of the ladle to extract as much sauce while leaving solids behind.
-
9
Alternatively, use a food mill for the same effect.
-
10
Once strained, return the sauce to the saucepan.
-
11
Finish the sauce: Place the peppercorns in a tea infuser or cheesecloth sachet, and add to the sauce.
-
12
Add the bourbon, brown sugar, vinegar, ginger, mustard and maple syrup.
-
13
Bring to a boil, then reduce heat and simmer, stirring frequently to prevent sticking or scorching, until thickened, about 30 minutes.
-
14
Remove the sachet of peppercorns, and remove sauce from heat.
-
15
Fill and close the jars: Using canning tongs, remove the jars from the canner, carefully pouring the water back into the canner.
-
16
Set next to the sauce in the saucepan.
-
17
Turn the heat under the canner to high.
-
18
Use a ladle to pour the sauce into the jars through a canning funnel, leaving 1/2-inch headspace at the top.
-
19
Run a clean chopstick around the inside of the jar to dislodge any trapped air.
-
20
Wipe the rims of the jars with a damp paper towel.
-
21
Place the lids on, and screw on the rings until just finger-tight.
-
22
Seal the jars: Using canning tongs, gently transfer the jars to the canner, taking care to keep them vertical.
-
23
When all the jars are in the canner, there should be at least 1 inch of water covering them; if you need more, add water from the kettle until the jars are sufficiently covered.
-
24
Bring the water to a full rolling boil, and process for 10 minutes.
-
25
Remove and cool: Using canning tongs, gently remove the jars from the canner and transfer them to a kitchen towel or cooling rack, again keeping them vertical.
-
26
Do not set hot jars directly on to cool counter surfaces.
-
27
Leave to cool, undisturbed, for at least 12 hours.
-
28
If any of the jars do not seal when cool, reprocess using the method above, or refrigerate and use immediately.
-
29
Label and store: Add a label to the lid or side of your jar, noting the date it was canned.
-
30
Remove the rings and store jars in a cool, dark place for up to one year.
-
31
Refrigerate after opening.
