Yields will vary based on the water content of the tomatoes.

Before beginning, wash tomatoes, cut away stems and discolored portion of tomatoes.

1. Blanch and peel (and deseed if desired) the tomatoes. If not deseeding, you may leave the tomatoes whole.
2. Quarter 1/6 of the tomatoes.
3. Place the quartered tomatoes in a pot and heat the pot while crushing the quartered tomatoes with a spoon, exuding the juice.
4. After the quartered tomatoes are boiling, slowly add remaining whole or halved tomatoes, stirring them in to prevent burning and maintaining a boil. The tomatoes will soften with heat and do not need to be crushed.
5. After all tomatoes are added, boil five additional minutes.
