"We were camping, and I didn’t have enough milk for my usual blueberry muffin recipe,” recalls Dorothy Ross of Ear Falls, Ontario. “I did have some sour cream and a bit of rhubarb, so I used those. The muffins were awesome, and now I make them often!”

Rhubarb

If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.

Blueberries

If using frozen blueberries, use without thawing to avoid discoloring the batter.
