in muffins.
In Muffins, Watermelon provides natural sweetness and moisture that shape the batter and rise. Its juice hydrates the flour and activates the leavener, but its low fiber means it contributes little structure; a swap must supply comparable sweetness and hydration without overwhelming the batter so the muffins dome and hold together rather than sinking.

adjustment for this dish
Pineapple's bromelain destroys the gluten network muffins need for the tender dome. Swap 1:1 cup but heat the puree to 180 F for 4 minutes and cool to 40 F before folding in. Pineapple also runs sweeter than watermelon, so cut sugar by 1.5 tbsp per cup. Stop at 8 strokes total when you fold the batter - overmix doubles the pain.

Strawberries

Red and refreshing in summer dishes

adjustment for this dish
Strawberries carry extra pectin that pulls the batter tighter as it rests, which suits muffins. Swap 1:1 cup without the sieve drain watermelon requires, but still cap the fold at 10 strokes. The dome rises roughly 15% higher than watermelon muffins because the pectin stabilizes the rise; rest 5 minutes in the tin before turning out.

Papaya

Sweet tropical fruit, similar juicy texture

adjustment for this dish
Papaya's papain shreds the gluten that supports the dome. Swap 1:1 cup simmered 5 minutes at 180 F and cooled to 40 F. Papaya runs sweeter and thicker than watermelon, so reduce the liquid in the recipe by 2 tbsp per cup of papaya and keep the fold to 8 strokes. The streusel browns faster here than on watermelon tops - check at 14 minutes.

Cucumber

adjustment for this dish
Cucumber runs 96% water vs watermelon's 92% and carries almost no sugar. Swap 1:1 cup peeled and pureed, then drain 20 minutes and use only the pulp. Add 2 tbsp sugar per cup of cucumber to compensate for the missing sweetness, and fold with 8 strokes - the thinner puree over-hydrates gluten faster than watermelon does.

technique for muffins
technique
Watermelon puree in muffin batter wants exactly one thing from you: stop mixing. The fruit's 92% water content hydrates gluten fast, and 12 strokes past blended turns the tender dome into a rubbery tunneled mess.
Fold the puree into the wet ingredients first, then add dry in two additions with 8-10 strokes total until streaks of flour just disappear - the batter should look lumpy. Unlike watermelon in scones, where you want dry cold pockets of fat, in muffins the puree should emulsify fully into the oil so the crumb stays moist three days out.
Scoop 1/3 cup batter into paper-lined tins filled two-thirds, sprinkle streusel if using, and bake at 400 F for 5 minutes then drop to 375 F for 15 more. The initial blast sets the dome before the center rises.
Rest in the tin 5 minutes before turning out; the bottoms are fragile while hot because the puree keeps them damp longer than a standard batter.
pitfalls to avoid
watch out
Don't overmix past 10 strokes; watermelon puree hydrates gluten fast and the dome turns into a rubbery tunneled tin of sadness.
watch out
Avoid filling liners past two-thirds - the high moisture batter climbs fast at 400 F and spills over the paper cup before the tops set.
watch out
Fold the puree into the wet ingredients first, not the dry, or the flour clumps around fruit chunks and the streusel sinks.
watch out
Rest 5 minutes in the tin before turning out; the damp bottoms tear if you rush them off the hot tin while the center is still steaming.
watch out
Skip the temperature drop and the dome collapses - 400 F for 5 minutes then 375 F for 15 sets the rise before the crumb over-hydrates.
