There are few things I find more satisfying in the kitchen than using up produce: the very notion of waste sends shivers down my spine. So, when I noticed a couple of apples wilting in the fruit bowl, I seized the opportunity to use them up. The result: these fruity, cinnamon-spiced, almond-topped muffins. I like to use spelt flour, with its rough-hewn nuttiness, here but you can use regular plain flour instead; the muffins won’t have the same wholesome heft, but there’s nothing wrong with a lighter-crumb either...
