Ingredients
Directions
Prepare the vegetables
Chop the onions, cucumbers, cauliflower (or cabbage), green tomatoes, and red peppers, but not too fine.
Mix the chopped vegetables with salt.
Scald them in 3 pints of vinegar and 3 pints of water.
Once well scalded, drain the vegetables from the vinegar.
Make the dressing and combine
In a separate bowl, mix 6 pints of vinegar, 2½ cups of brown sugar, ¾ pound of ground mustard, 1 ounce of turmeric, ½ pint of olive oil, and ¾ cup of flour.
Combine the mustard, flour, oil, and turmeric with 1 pint of cold vinegar.
Stir this mixture into the boiling vinegar while adding the sugar and spices.
Add celery or celery seed for extra flavor if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sharp acidity that defines the pickle and helps preserve the vegetables.
- Flour
- Thickens the vinegar mixture into a smooth, spoonable sauce when heated.
- Brown sugar
- Adds sweetness that balances the sharp acidity of the vinegar.
- Ground mustard
- Contributes the pungent, sharp flavour characteristic of mustard pickles.
- Turmeric
- Gives the chow chow its yellow colour and a mildly bitter, earthy aroma.
- Olive oil
- Adds fat that gives the sauce a smoother, richer mouthfeel.
The step that matters
Stir the flour mixture into the boiling vinegar. Flour clumps if added dry or to hot liquid unmixed. Blending it first with cold vinegar makes a smooth slurry, which then thickens evenly when stirred into the boiling liquid.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, cauliflower, tomato, pepper, vinegar, sugar, mustard):
- Broccolifits better

- Onionthe original
Fit is the average pairing score against cucumber, cauliflower, tomato, pepper, vinegar, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
