Peel, seed, and grate large cucumbers. Drain the pulp in a sieve, measure, and to a quart allow two green peppers, seeded and minced, two teaspoonfuls of salt, a grated onion, a gill of grated horse-radish and a scant half teaspoonful of cayenne. Mix all well together, add a pint of vinegar, bottle the catsup and seal.
