Although we all know ketchup as the thick tomato-based condiment served with french fries, it started out as a pickled fish condiment popular in China that then evolved into an accompaniment made from a variety of ingredients from nuts to mushrooms. It wasn't until New Englanders in the late 1700s introduced a tomato version that the name ketchup grew to become synonymous with tomatoes.

This is a non-tomato ketchup made of mushrooms and spices. It is a great condiment to serve with meats and poultry. Make sure you plan ahead—the mushrooms need to stand 24 hours during the first step of the recipe.

"Fancy Pantry" by Helen Witty (Workman)


  • 1 1/2 pounds mushrooms, firm and fresh

  • 1 1/2 tablespoons pickling salt

  • 1 ounce dried boletus mushrooms

  • 3 cups hot tap water

  • 2 cups white wine vinegar

  • 3 large shallots, or 1 small onion, peeled

  • 1 clove garlic, peeled

  • 10 whole allspice berries, or 1/4 teaspoon ground allspice

  • 4 whole cloves

  • 3 large blades mace

  • 2 bay leaves

  • 1/2 teaspoon ground ginger

  • 1/2 teaspoon freshly ground black pepper

  • 1/4 cup dry sherry, or medium sherry

Steps to Make It

  1. Wipe fresh mushrooms clean with a damp cloth, or brush them clean. Avoid washing them if possible; if it is necessary, swish them rapidly through a bowl of water and lift and drain them promptly. Trim off any discolored stem ends or damaged portions.

  2. Slice the mushrooms thinly (a food processor fitted with the thin-slicing disc makes short work of this task) and mix them thoroughly with the pickling salt in a ceramic bowl. Cover mushrooms with a cloth and let them stand 24 hours, stirring occasionally. They will become very dark (the finished ketchup will be approximately the color of black bean soup).

  3. At least an hour before the end of the salting period, combine the dried boletus mushrooms with the 3 cups hot tap water; let them stand, covered, until completely soft.

  4. Lift the dried soaked mushrooms from their liquid with a slotted spoon (this is to eliminate any grit that may be in the liquid) and place them in the bowl of a food processor or blender. Let soaking liquid settle for a minute or two, then carefully pour it over the mushrooms, stopping before any grit is poured out. Puree the soaked mushrooms, then pour the puree into a saucepan.

  5. Without rinsing the processor or blender container, puree the salted mushrooms; add this puree to the saucepan.

  6. Place about 1/2 cup of the vinegar in the blender and add the shallots and garlic; process them to a puree. Add this puree to the mixture in the saucepan, together with the rest of the vinegar, the allspice, cloves, mace, bay leaves, ginger and pepper.

  7. Bring the mixture to a boil over medium-high heat, lower heat, and simmer the ketchup, uncovered, stirring it often, for 1 to 1 1/2 hours, or until the tiny fragments of mushroom are very soft, almost jelly-like, and the ketchup is thick.

  8. To test for correct consistency, pour a spoonful onto a saucer and let it stand 10 minutes, with the pot off the heat; if very little or no liquid seeps from the solids, the ketchup has thickened enough. If it does not pass this test, resume the cooking for as long as necessary.

  9. Press ketchup through a sieve to remove the bay leaves and whole spices, then puree it again, in batches if necessary, in a blender or food processor, running the machine until the texture is velvety smooth.

  10. Return ketchup to the rinsed-out pan and bring it to a full boil again over medium-high heat, stirring it constantly. Stir in the sherry.

  11. Ladle the boiling-hot ketchup into hot, clean half-pint or pint canning jars, leaving 1/4 inch of headspace. Seal jars with new 2-piece canning lids according to manufacturer's directions and process for 15 minutes (for either size jar) in a boiling-water bath. Cool, label and store the jars. Let ketchup mellow for a few weeks before serving it. This keeps for at least a year in a cool pantry.

Use Caution When Blending Hot Ingredients

Steam expands quickly in a blender, and can cause ingredients to splatter everywhere or cause burns. To prevent this, fill the blender only one-third of the way up, vent the top, and cover with a folded kitchen towel while blending.
