I'd forgotten how nice lemon slice could be. Especially when made with homegrown lemons picked straight from the tree. Mmmm. The scent of fresh lemons. Lemon oil on your hands. For me the key to this recipe is the huge amount of lemon zest. The original Women's Weekly recipe had just one teapoon. I've doubled the original recipe, because what would one do with a leftover half tin of condensed milk anyway?* The doubled recipe makes enough to take for morning tea at work and some for home. Or for a good showing at a cake stall. And it contains three table spoons of lemon zest which in my view adds a certain excitement.
You will need:
For the slice
1 cup (or tin) of sweetened condensed milk
500g Marie biscuits (2 packets)
3 tablespoons grated/zested/finely chopped lemon rind with no pith attached. I use a sharp vegetable peeler and then chop with a knife
2 cups dessicated coconut
For the icing
3 1/2 cups of icing sugar
6 tablespoons of strained lemon juice
coconut to put on top (if I have it I used the standed or flaked one here)
Wash lemons and prepare lemon zest.
Crush Marie biscuits. I don't have a food processor so I place the biscuits in two plastic bags and bash and roll with the rolling pin. This is how my mum did it when I was a kid. But a food processor is also quite effective, just don't over process. Some lumps are good for texture here.
Mix biscuit crumbs, lemon zest and coconut.
Melt butter and condensed milk together. Stir and add to the dry mix. Combine well.
Line a big roasting or slice tray(s) with baking paper. Pour in slice mix. Place a piece of baking paper over the top and press down with hands. Then use a flat sided glass to roll out and compress well. Place in fridge.
Juice enough lemons to provide 6 tablespoons of strained juice.
Mix juice butter and icing sugar together until it has a smooth consistency.
Ice the slice and sprinkle with coconut. Press down gently with that bit of baking paper from before.
Refrigerate overnight and then lift out of pan and cut into small(ish) squares with a big knife.
* I know, I know. One could eat half a tin of condensed milk. Or let your child eat it. Or fight the cat for it. Or turn it into lemon cheesecake mix and repeat as before.
