quinces substitute
in cake.
Quinces folded into Cake batter adds natural sweetness and moisture that keeps the crumb tender. The substitute must match its water content and flavor.

adjustment for this dish
Pears carry roughly 84% water to quince's 83% but almost no pectin, so swap 1:1 by piece yet skip the 20-minute syrup poach — pears soften fully in the 25-30 minute bake. Drop the recipe's sugar by 2 tablespoons because ripe Bartletts are twice as sweet raw, and still dredge the 1/4-inch dice in flour to keep the tender crumb from sinking.

adjustment for this dish
Apples run 86% water and carry malic acid that quince lacks, so swap 1:1 by piece but add 1/4 teaspoon baking soda per cup of flour to neutralize the acid, or the baking powder alone will leave the crumb dense. Firm varieties (Honeycrisp, Braeburn) hold shape through the bake; avoid McIntosh which collapses and weeps into the batter.
technique for cake
technique
Quinces in cake refuse to soften during the 25-30 minute bake the way softer fruit does, so they must be poached in sugar syrup at 180F for 20 minutes before you fold them into the batter or the toothpick test will come out clean while the fruit itself stays chalky. After poaching, cube the flesh to 1/4-inch dice and pat dry so surface moisture does not bleed into the crumb and sink the pieces to the pan bottom.
Dredge the cubes in 2 tablespoons of the recipe's flour before folding them in to keep them suspended. Because quince purees carry roughly 12-15% natural pectin, folding in more than 1/2 cup of puree per 9-inch pan will toughen the gluten structure and flatten the rise; the baking powder simply cannot lift the denser batter.
Unlike in pancakes where raw grated quince is fine because the griddle finishes cooking it in under 3 minutes, cake demands that pre-poach step. Sift the dry ingredients twice so the fruit-heavy batter still reads tender when sliced cool.
pitfalls to avoid
watch out
Don't fold raw quince cubes straight into the batter — they stay chalky through the full bake and the toothpick lies; poach them in syrup at 180F for 20 minutes first.
watch out
Avoid exceeding 1/2 cup quince puree per 9-inch pan because the natural pectin tightens the gluten and the baking powder cannot compensate for the extra density.
watch out
Skip rinsing the poached cubes; washing away the syrup coating lets surface moisture sink pieces to the pan bottom and leaves a gummy layer under the crumb.
watch out
Don't substitute quince paste for fresh without cutting the recipe's sugar by 3 tablespoons, or the creaming step will over-sweeten and collapse the rise.
watch out
Cool the cake a full 30 minutes in the pan before turning out — hot quince pieces bleed juice into the tender crumb and cause the slice to tear at the fold line.
