I was out of blueberry jam so I subbed orange marmalade. Then I was out of orange so I subbed grapefruit peel. Came out of the over not quite done, so I put the sugar on and back in for 5 minutes. OMG!!!!
I did not have any blueberry jam so subbed orange marmalade and used lemon/grapefruit for the sprinkle. Not quite done so I put them back in with the sugar on top. OMG!
These are really tasty! I decreased the melted butter in the muffins to 4 Tbs. instead of 6. It worked just fine. My husband also said the recipe is a "keeper." I mixed the butter, sugar & peel altogether & spooned it on the muffins. I thought it was easier. I also used lime zest instead of orange, because it is what I had on hand.
These are absolutely delicious. Including both berries and jam give the muffins so much moistness. I love the added crunch of the citrus sugar as well. You can read my full review at Taking On Magazines: http://bit.ly/13x8Ysj
These muffins are easy to make and yummy. I have used boxed mix in the past to make blueberry muffins, adding fresh blueberries to the mix, but this recipe is so simple. My husband loved them too, which makes them more of a keeper than the ease of the recipe. I'll make these gain. Yum!
