Homemade Quince Paste (Membrillo)

Quince paste is one of the noblest ways to preserve fruit. Quince's natural gelling agent (pectin) is so strong that when cooked slowly with sugar, it results in a sliceable, gummy-bear-like consistency without artificial additives. During cooking, the fruit pulp transforms from pale yellow to deep ruby red as sugars caramelize and pigments concentrate.

Instructions

1

Rub the fuzz off the quince and wash well. Core them (don't discard cores!) and chop the fruit.

Tip: The core contains the most pectin. Boil them in a cheesecloth bag with the fruit, then remove before pureeing to ensure a good set.
2

Place fruit in a pot, barely cover with water, and boil until soft (20-30 mins).

Tip: Add lemon juice now to prevent browning.
3

Drain the water (save for syrup!), and puree the fruit until completely smooth.

Tip: The smoother the puree, the more glass-like and homogeneous the result.
4

Weigh the puree: for every pound of puree, add 0.8 lb sugar. Return to heat and cook, stirring constantly.

Tip: Careful, the thick mass splatters! Use a long-handled spoon and gloves.
5

Cook (approx 40-60 mins) until the mass turns dark red, glossy, and leaves a clear trail on the bottom of the pot when the spoon is pulled through.

Tip: This evaporates the water. If not thick enough, it won't dry out.
6

If adding walnuts, mix them in now. Pour into parchment-lined or wet molds.

Tip: Thinner layers dry faster.
7

Let rest in a cool, airy place for days. Once the top is hard, flip it out to dry the other side.

Tip: Full drying can take weeks; this stabilizes the crystal structure.

Recipe FAQ

Why didn't it set?
You likely didn't cook it long enough, leaving too much water. Quince paste must be cooked until it leaves a trail in the pot.
Why did it mold?
It didn't dry out enough or was stored in a humid place. Sugar preserves, but only if water content is low.
