in muffins.
In Muffins, Yam provides both bulk and subtle sweetness that shapes the batter and rise. A good replacement cooks to a similar texture.

adjustment for this dish
Sweet potato's higher sugar browns the tops faster — drop the oven from 400°F to 385°F for the first 10 minutes, then bump back to 400°F so the dome sets without the crown scorching above the paper liners.
02
Cassava
10.0best for muffins1 cup : 1 cup
Dense and starchy, slightly sweeter
10.0
adjustment for this dish
Cassava must be peeled and parboiled before dicing because its raw compounds don't cook out in the 18-22 minute muffin bake. Its finer starch also tightens the batter, so fold in only 6 strokes instead of 10 to avoid the dome collapsing from overmixed gluten.
03
Taro

Dense and starchy, very similar texture
10.0
adjustment for this dish
Taro dices firmer than yam and holds its shape through the bake — you can dice taro to 3/8-inch (vs yam's 1/4-inch) for more visible pockets in the crumb. Taro's faint lavender bleeds slightly into the surrounding batter, which is a feature, not a flaw, in a paper cup.

Potatoes
10.01 cup : 1 cup
Neutral starch, less sweet
10.0
adjustment for this dish
Potatoes lack the sweet counterpoint yam provides, so add 2 tablespoons of sugar per cup of diced potato to the batter. Potato cubes also release less moisture, so the muffins come out slightly drier — brush the tops with melted butter as they cool to restore a moist crumb.
05
Plantain
3.31 cup : 1 cup
Starchy, use ripe for sweetness
3.3
adjustment for this dish
Plantain's high sugar browns the dome edges aggressively; use green plantain only and scoop the tins to just 2/3 full (not the 3/4 for yam) so the over-rising plantain doesn't overflow the liners and scorch against the tin's hot edges.
technique for muffins
technique
Muffin batter with yam wants a coarse 1/4-inch dice rather than the fine grate used for cake — the diced cubes stay intact through the 400°F oven and give each bite a tender starch pocket that supports a tall dome. Fold 3/4 cup diced yam into the batter with no more than 10 strokes after combining wet and dry; any more and the gluten tightens, collapsing the dome into a flat cap.
Scoop a generous 3 tablespoons per well into paper liners — fill the tin only 3/4 full or the tops will spread into each other instead of rising cleanly. Unlike yam in cake which needs a grated fine texture for a uniform crumb, yam in muffins rewards chunky pieces you can see in the cross-section.
Bake 18-22 minutes; the tops should spring back and a toothpick show moist crumb (not wet batter). If adding a streusel, sprinkle only after 8 minutes of baking so it doesn't sink into the rising dough.
pitfalls to avoid
watch out
Don't overmix once the wet hits the dry — more than 10 folds tightens the gluten around the yam pieces and the dome flattens into a tough cap.
watch out
Avoid filling the paper liners past the 3/4 mark; yam's extra moisture makes muffins expand more than plain batter and adjacent tops will fuse across the tin.
watch out
Skip pre-cooking the yam cubes — raw 1/4-inch dice finishes tender in the 18-22 minute bake, but pre-cooked cubes turn mushy and sink through the batter.
watch out
Don't sprinkle streusel before baking starts — add it at minute 8 or the topping sinks into the rising batter and disappears into the moist crumb.
watch out
Use room-temperature eggs — cold eggs seize the batter fat around the yam cubes and leave lumpy streaks through the finished muffin.
