English Piccalilli, sometimes referred to as English Mustard Pickle, is a savory relish made from cauliflower, gherkins, and pearl onions, pickled with malt vinegar, sugar, and salt, and spiced with dry mustard and turmeric. It's easy to prepare and makes an amazing accompaniment to various cold and hot dishes.
10ounces(283 grams) pearl onions, peeled (See Tip 1)
2TablespoonsKosher salt
3 cups(24 ounces, 710 ml) malt vinegar, divided
¾cup(5.25 ounces, 149 grams) granulated sugar (See Tip 2)
3Tablespoonscornstarch (See Tip 3)
6Tablespoons Dry mustard (See Tip 4)
3Tablespoonsturmeric powder
Instructions
Combine cauliflower florets, sliced gherkins, and pearl onions in a large bowl. Sprinkle on Kosher salt; stir to combine. Cover with plastic wrap and let sit at room temperature overnight.
The next day, transfer vegetables to a colander; rinse well with cold water. Drain well (See Tip 5).
Whisk together cornstarch, dry mustard, turmeric, and 1 cup of vinegar in a small bowl. Set aside.
Add the remaining 2 cups of vinegar and sugar to a large saucepan. Heat over medium heat until sugar has dissolved, about 2 minutes. Add cornstarch mixture. Whisk or stir constantly until bubbly and thickened, about 2 minutes.
Add the vegetables; stir to combine. Heat over medium heat, stirring occasionally for 10 to 12 minutes or until cauliflower becomes tender. Remove from heat. (See Tip 6)
Transfer to sterilized jars; seal and process in boiling water (See Tip 7)
Store in a cool, dark place for 6 to 8 weeks to allow the flavors to meld together. Once opened, refrigerate.
Yield: 3 12 ounce jars and 2 8 ounce jars.

Tips/Notes
To peel pearl onions easily, add them to a pan of boiling water. Boil for 3 minutes; transfer to ice water to stop cooking. When onions are cool enough to handle, slice off the root end and pinch to release the onion from the peel.
If you like a sweeter Piccalilli, you might want to add additional sugar to taste.
Cornstarch and corn flour are the same thing. Both are thickening agents.
I used Coleman's mustard powder, which is traditional English mustard powder. It's generally readily available in grocery stores. If you can't find Coleman's, you can use any mustard powder.
Taste the cauliflower; if it is too salty, soak in cold water for one hour. Drain thoroughly.
If the sauce seems too thick, add a tablespoon or two of additional malt vinegar to the mixture.
The boiling water should cover the jars. Let them process for about 10 minutes. When you remove the jars, you should hear the pop that indicates that the jars are sealed.
