soursop substitute
in cake.
Cake relies on Soursop for natural sweetness and moisture. When substituting, focus on matching what matters most for the crumb structure.

adjustment for this dish
Pineapple runs hotter on acid (pH 3.3 vs soursop's 3.7) and its bromelain enzyme will chew up gluten strands if raw. Use canned or cook fresh puree 5 minutes to kill the enzyme, then swap 1/2 cup pineapple per 1 cup soursop and drop 2 tablespoons from your batter's other liquid; the crumb stays tender but rise gains a half-centimeter from the sharper acid hitting baking soda.

Strawberries

Tart-sweet, blend with coconut milk
10.0
adjustment for this dish
Strawberries hold about 91% water versus soursop's 81%, so a 1:1 cup swap floods the batter. Macerate 1 cup strawberries with 2 teaspoons sugar for 20 minutes, drain off the juice, then fold the solids in; toothpick clean time drops to 30 minutes because there is less pulp to dry out and the crumb gets a pink-flecked moist crumb rather than dense gumminess.

Mangoes

Sweet tropical for smoothies
5.0
adjustment for this dish
Mangoes match soursop's moisture near 83% but bring 14% sugar versus soursop's 9%, so a 1:1 cup swap overshoots sweetness. Cut the recipe's sugar by 3 tablespoons per cup of mango puree, sift cake flour twice for extra tenderness against the heavier puree, and expect baking powder to do more lifting than baking soda since mango's pH of 4.0 is milder than soursop's acid bite.
technique for cake
technique
7, so a cup of it dumps both liquid and acid into your batter in ways sugar alone cannot mimic. That acid activates baking soda immediately, which is why creaming butter and sugar for 4-5 minutes at medium-high gives you the only reliable head start on rise before the leavening fizzes out in the bowl.
Sift the dry ingredients twice and fold the soursop puree in at the very end with no more than 15 strokes, or the gluten you just built will tighten the crumb into gumminess. Unlike cookies, where a little extra moisture just spreads the dough flatter, cake geometry depends on trapping steam in a set structure, so pour batter into a greased and lined pan only three-quarters full and bake at 350 degrees until a toothpick pulls clean with two or three tender crumbs, usually 32-38 minutes.
Cool in-pan for exactly 10 minutes before turning out, because soursop-heavy cakes stay moist and will tear if you rush.
pitfalls to avoid
watch out
Don't dump soursop puree into the batter before creaming is finished; the acid kills rise in under 90 seconds if baking soda is already hydrated without cushioning.
watch out
Avoid substituting soursop cup-for-cup for mashed banana without reducing other liquids by 3 tablespoons, or the crumb turns wet and the toothpick test never comes clean.
watch out
Reduce oven temperature by 15 degrees if your pan is dark metal; soursop sugars caramelize fast and the edges brown before the center sets, leaving a gummy moist core.
watch out
Skip overmixing after the fold stage; more than 20 strokes develops gluten and the tender crumb collapses into a dense stripe at the bottom of the pan.
watch out
Cool in-pan only 10 minutes before turning out; leaving a soursop cake longer traps steam against the bottom and the slice tears when you lift it.
