Preheat your oven to 180 Fan / 200 C / 400 F / Gas 6 and line a 12 cup muffin tin with cases
In a small bowl or jug whisk together the milk, vinegar and oil and set aside
In a large bowl whisk together the flour, sugar, bicarb, cinnamon and nutmeg
Add the wet ingredients to the dry and stir together until well mixed, stirring up from the bottom of the bowl to make sure there are no flour 'pockets'
Stir in the grated carrot and sultanas, mixing well
Spoon into the muffin cases, filling each one roughly 3/4 full. The mix should make exactly 12 muffins
Bake for 25 minutes until golden and springy to the touch and a cocktail stick inserted into the centre of one of the muffins comes out clean with no raw batter clinging to it
Leave to cool in the tin for 5-10 minutes before lifting out onto a wire rack to cool completely
Once cool make the frosting - mix the icing sugar with enough water to make a thick, spreadable paste. Add the water a little at a time. If you make it too thin, simply add a bit more icing sugar
Add a few drops of lemon extract to taste
Use a teaspoon to put a little of the icing on top of the muffin then use the back of the teaspoon to spread. Sprinkle over the chopped pistachios before the icing dries
Store in an airtight container at room temperature. Any extras can also be frozen
