"It happens every February. Standing in line at my local produce market with a basket of roots and greens, I smell strawberries. I buy a pound but, sadly, they're never as good as summer berries and so into the jam pan they go. Paired with a few Meyer lemons, the end result is a loosely set spread that evokes strawberry lemonade."
Wash and dry the lemons. Trim off the ends and slice the fruit in half from top to bottom. Using a sharp paring knife, cut out the pithy center core of each lemon half and remove the seeds. Reserve both the pithy cores and seeds (we'll be using them as a pectin source). When all lemons have been trimmed, slice the halves into thin half-moons, place in a glass or plastic bowl, and cover with 2 cups of water. Gather up the reserved seeds and pith and tie them up tightly in the center of a cheesecloth square. Add this bundle to the lemon slices. Cover and set aside.
While the lemon slices soak, wash the strawberries and chop them well. Place them in a separate glass or plastic bowl and add the sugar. Stir to combine and cover. Let both bowls sit for at least an hour and up to 3 hours. Stir the strawberries once or twice, if possible, to help the sugar draw out their liquid.
When you're ready to cook the marmalade, prepare a boiling water bath and four half-pint jars. Place four lids in a small saucepan of water and bring to a gentle simmer.
Pour the lemon mixture and the strawberries mixture into a wide, nonreactive pan. Bring to a boil and cook over medium-high heat for 30 to 40 minutes, stirring regularly. The marmalade is done when it reaches and holds 220° F, looks shiny, and is able to pass the plate test.
Funnel the finished marmalade into the prepared jars, leaving ½ inch of headspace. Wipe the rims, apply the lids and rings, and process in boiling water for 10 minutes.
