Yellow Pickle

Ingredients

Directions

Prepare the vegetables

  1. Cut the green tomatoes and peppers, discarding the seeds and any imperfections.

  2. Soak the tomatoes and peppers in strong brine for 1 hour.

  3. Drain the tomatoes and peppers.

  4. Cook the tomatoes and peppers in fresh hot water until tender.

  5. In separate pots, cook the cauliflowers (broken into small pieces) and peeled onions until tender.

  6. Drain the cauliflowers and onions.

Make the pickle

  1. In a large kettle, combine the vinegar, mustard, flour, and turmeric to form a smooth paste with a little vinegar.

  2. Stir the paste into the remaining vinegar.

  3. Bring the mixture to a boil.

  4. Add all the cooked ingredients to the vinegar mixture.

  5. Cook slowly for 1 hour or more, stirring often.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Thickens the vinegar mixture so the pickle becomes smooth and thick.
Dry mustard
Adds sharp, pungent flavour that balances the vinegar and sugar.
Cider vinegar
Provides the acidity that preserves and sharpens the pickle.
Turmeric
Gives the pickle its characteristic yellow colour.
Green tomatoes
Supply bulk and a firm texture that holds up during long simmering.
Cauliflowers
Add bulk and a firm, crisp-tender texture to the pickle.

The step that matters

Make a smooth paste before adding the liquid. Flour and mustard clump if dumped into hot liquid directly. Mixing them into a paste with a little cold vinegar first lets the starch disperse evenly, so the pickle thickens smoothly without lumps.

Swap the cauliflower
