Very Good Muffins

I have been trying different recipes to find the best and this one is pretty close. It makes a dozen large muffins.

2.5 cups flour
3 teaspoons baking soda (if you use self raising flour cut this to 1.5 tspns)
half a cup of sugar
1 tsp salt
just over half a cup of butter (about 3 oz)
2 eggs
cup of milk
1 tsp orange zest

1.5-2 cups of some filling, blueberries, raspberries chocolate chips etc

Topping
zess of one lemon (or orange or lime)
qtr cup sugar
mix until sugar turns the colour of the zest

Preparation
Heat oven to 400
Put flour, sugar, salt, baking powder into a bowl and cut in butter to crumb
Seperate eggs from white into two bowls.
Add milk to yolk and beat lightly
Beat whites until fluffy
Put berries on a flat plate and sprinkle icing sugar or sugar
put berries in flour micture and using wooden spoon gently mix
then add all liquid and mix very carefully, basically your folding it until its just moist (not stirring)

Grease your cups and divide mixture and add lemon topping and bake for 20 minutes until golden brown

remove from pans onto a rack if possible and let cool before moving to plate.
