Old Style Farm Marmalade

This is marmalade the way it was made before commercial pectin existed. Oranges, sugar, lemon juice, and water simmer for three hours until the natural pectin in the orange rind does its job and the whole batch sets into a thick, spreadable preserve.

The orange rind gets boiled separately for ten minutes first. This softens the peel and starts to release its pectin, which is concentrated in the white pith. Then the chopped oranges, lemon juice, and sugar go in for the long, slow simmer.

Three hours sounds like a lot, but most of that time is hands-off. Just stir occasionally to prevent sticking as the liquid reduces and thickens. The mixture will darken gradually as the sugar caramelizes and the rinds become translucent.

The wrinkle test tells you when it’s ready. Drop a small amount on a cold plate, let it cool briefly, and push it with your finger. If it wrinkles, you’ve hit the set point. A candy thermometer reading of about 220°F (104°C) confirms it.

Chef Tips

• Use a wide, heavy-bottomed pot. More surface area means faster evaporation and a shorter path to the set point.
• Sterilize your jars while the marmalade simmers. They need to be hot when you ladle in the hot marmalade.
• Lemon juice isn’t just for flavor. The acid helps activate the natural orange pectin and ensures a proper set.
• Skim any foam off the surface before ladling into jars for a clearer, more attractive preserve.

Variations

• Add a cinnamon stick or a few whole cloves during the simmer for a spiced marmalade.
• Mix in grapefruit rind along with the orange for a three-citrus version.
• Stir in a splash of whiskey after removing from heat for a boozy, gift-worthy preserve.
