The simple, manual technology of this press makes smoother, silkier tomato and apple sauce than even the most expensive food processor. Why? Because the top is a small, stainless steel food mill, a device used for nearly 100 years by top chefs and home cooks. Fill the hopper with your desired ingredients and turn the handle to puree them directly into the mason jar. No more tedious tomato skinning or seeding for you: the blade presses the produce, while the strainer lid keeps seeds and skins out of the sauce. (Apples do need to be peeled and cored.) The result: a divinely velvety consistency. Store it right in the jar—for leftovers or for canning.
