Grater preferably a microplane grater, for the optional lemon zest.
Ingredients
4lbsripe green tomatoeswashed, cored and chopped roughly
¼cupcow parsnip seedsoptional-if you don't have them, skip it.
¼cupfresh gingerfinely chopped
2cupscider vinegar
1cupsugar
Kosher saltto taste
a few scrapes of fresh lemon zest optional
Instructions
Combine all ingredients in a wide pot or heavy bottom saucepan like a 10 inch brazier or stock pot and cook on high. Bring to a boil on medium-high heat, then turn the heat down to medium-low, stirring occasionally, until the pan is nearly dry, roughly 1 hour.
Transfer the mixture to a high-speed blender and puree using the accelerator attachment until you get a velvety smooth puree, if you have to, add a little hot water to make it smooth and help the blade catch, you can always cook the water off slowly in a wide pan or add some pectin to thicken it if it's too loose.
Pass the mixture through a fine mesh strainer or chinois, stir in the lemon zest to taste if using, season with salt until it tastes good to you (start with a teaspoon and go from there) transfer to a labeled, dated container and refrigerate until needed. *See note.
Notes
Pureeing and straining the jam is optional
This was originally a restaurant dish, and I like smooth purees. Don't be intimidated by that. It's totally fine to leave this chunky or pureed and not passed through a strainer if you want-it's up to you. You can also puree the tomatoes in a food processor before cooking.
