After I had decided to bake this muffin I then realised that there was not any lemon left in the fridge. So, I baked orange muffins instead substituted lemon juice with orange juice and lemon zest with orange zest! They turned out perfectly in term of look and taste.
Few weeks later, I thought of eating muffin and baked some lemon muffin followed the recipe I used for orange muffin exactly. But the taste was not that good compared to orange muffin, maybe because I am an orange eater?
