Of course you can! Although if you by some bizarre coincidence ever meet my Dad, don't tell him! It's an old family recipe and I only found out the recipe a few years ago after my Dad considered me worthy (he's a superb cook and baker!)
The recipe is easy:
2 1/2 dl sugar (caster / muscovado / dark muscovado - according to preference)
1 1/2 dl syrup
2 1/2 tsp of each ginger, cinnamon and cloves
3/4 tsp of bicarb mixed with a small amount of water
250g butter
1 egg
Around 1 litre flour (at a guess it's around 1lb flour)
Put the sugar, syrup and spices in a sauce pan and melt together.
When melted together take off the heat and add the bicarb mix.
Melt the butter and add.
Whisk the egg lightly and add
Pour into a large mixing bowl and then add sifted flour little by little until you have a soft dough (not too stiff as you will need to add flour when rolling out).
Put clingfilm over the bowl and leave in cool place (eg fridge) for at least 12 hours.
Take dough out 1 hour before rolling. Roll as thin as possible (1mm thick if you can) and cut out shapes (stars, hearts etc).
Bake in a 200°C oven for 4-5 minutes. They burn really easily so keep an eye on them.
Leave on rack until completely cool and keep in tins...
Swedish recipes tend to be by volume rather than weight. 1 decilitre equals 100ml...
