Yes, buy a bottle of blue gel colouring, and just use a tiny drop, kned it in, add more if you need to. The colour develops as you knead, so don't add too much. Wear latex gloves, it stains your hands. I have shopped here before. They may sell fondant ising as well, although our local Sainsbury's has that.
Mud Cake: (maybe its not called mud cake in England?.. Fudge cake?)
250g butter
150g white or dark chocolate
2 cups caster sugar
1 cup milk
- Microwave or melt in saucepan the above ingredients until smooth (not boiling). Alow to cool for 10 mins or so.
sift in:
1 and 1/2 cups plain flour
1/2 cup SR flour
whisk or beat with electric mixer until well mixed
Mix in:
2 eggs
1 teaspoon vanilla essence
Pour into greased 20cm round pan (or equivilent) and bake at 180 degrees celcius for 45 mins. Check with a skewer, return to oven if needed, cover with foil if its browning. The skewer should have sticky little crumbs on it, but not runny cake mix.
Getting the cooking time right is the trick with this cake. On my old oven it cooked in 45 mins...new oven is about 1 hour 10 mins...but you just need to keep checking it. It is always a bit solid and seriously 'muddy' in the middle, but so long as its is solid and not runny its good. I always make this for birthday cakes. Its really easy to cut and shape, and doesn't sag under weight of the icing. It freezes well, but defrost before icing.
You might need to make two for a tall baptism cake. I would use a carving knfe to flatten off the top (it will be domed) of both cakes, then just stack them with nothing in between, or stick a couple of wooden skewers in if you think they will move around.
Stick the first layer of fondant to the cake with either strained, warmed apricot jam, or a bit of the fondant icing mixed with water to make a spreadable paste/liquid. Paint all over the cake with a pastry brush.
