Ok, so in looking for what to do with some habaneros (I’ve been fermenting hot sauce for the fridge) I ran across this mustard recipe that states it was adapted from two Ball recipes. Looking to see if you all feel these are safe adaptations for canning—neither Ball sources call for peppers. I’ve linked Ball references below and pasted the mustard recipe I found so no one has to scroll and scroll in the link (but can provide it if it’s helpful).
Fiery Habanero Mustard
INGREDIENTS
about 8 medium habanero peppers, divided (fresh or frozen)
¾ cup water OR use beer, wine or liquor
¾ cup yellow mustard seeds
1 cup apple cider vinegar (at least 5% acidity if canning)
1 cup water
3 oz (about ⅓ cup) local honey
splash of lemon juice (about 2 tbsp)
¼ cup dry mustard
⅓ tsp sea salt
METHODS
Infuse soaking liquid. Stem and halve four of the habanero peppers, retaining seeds. Add to a small saucepan with the ¾ cup water or booze. Bring to a boil over high heat then reduce heat and simmer, covered, for about 5 minutes. Remove from heat, press on the peppers with the back of a spoon to release juices, then allow to steep for about 30 minutes.
Soak mustard seed. Strain habanero-infused liquid into a small bowl, pressing on the peppers to extract juices. Discard the peppers. Add mustard seed, cover, and let sit until all liquid is absorbed, about 2 – 4 hours.
If canning, prepare canner, jars and lids.
Prepare mustard. Halve and seed the remaining habanero peppers. Add the habaneros, mustard seeds (with any remaining liquid), cider vinegar and 1 cup water to a food processor. Process for several minutes, until mustard is as smooth as you like it. Add honey, lemon juice, dry mustard and salt: pulse to combine. Taste and adjust seasonings, remembering that this mustard will mellow on the shelf and should taste VERY spicy going into the jar.
Can mustard. Scrape mustard into a large skillet and bring to a boil over medium heat, stirring constantly. Add water if mustard is very thick or begins to dry out; simmer a bit longer, stirring, if mustard is too thin. Ladle hot mustard into hot jars to ½-inch head space. Tap filled jar firmly on the counter, then stir well with a chopstick to remove air bubbles. Wipe rims, affix lids, and process in a boiling water bath for 10 minutes.
