Homemade Strawberry Jam (naturally paleo and vegan)

(~6 1/2 cups smashed) rinsed, hulled really sweet strawberries

honey or Grade A maple syrup for a vegan version (1/3 cup or 67 grams granulated sugar for a non-paleo version also works but you'll need less cooking time)

lemon zest

freshly squeezed lemon juice
