Can you substitute the bananas in the Banana Butterscotch Muffins with strawberries or blueberries?
Nigella's Banana Butterscotch Muffins(from NIGELLA EXPRESS) are banana muffins studded with butterscotch chips (or you could use white chocolate chips if butterscotch ones are not available). Bananas are good for baking as they are high in natural fruit sugars. This helps to sweeten the muffins but also these sugars attract moisture which helps to keep the muffins moist. The sugars also hinder the development of gluten in flour, giving the muffins a fine, soft crumb.
Bananas also have a lower level of water than most other fruits, giving a fairly thick texture when pureed. If you use a fruit with a high water content, such as blueberries or strawberries, then the muffins would not be as sweet or soft. Pureed blueberries also tend to give baked goods a greyish hue once baked, which may not be that attactive. You could use whole blueberries in the muffins instead of the butterscotch chips. Use fresh (not frozen) blueberries and toss them with a little of the flour from the recipe before folding them into the muffin batter.
