Linzer biscuits are just about the most festive thing that you can make at this time of the year. Spiced, nutty pastry filled with bright red raspberry jam, and with snow-like icing sugar. And they are shaped like stars. Sort of like screaming good cheer at the top of your voice, isn’t it?
Actually, Linzers have a rather ancient pedigree. They are closely based on the famous Linzertorte from the Austrian city of Linz, which is said to be one of the oldest (or indeed, the oldest) cakes in the world, with recipes found from as far back as the 1600s. It is made from a rich, nut pastry and then filled with a dark fruity jam, often blackcurrant, and then finished with a lattice top. These biscuits are essentially a variation on that theme, but with the lattice top replaced with some nifty cookie-cutter action. I’ve gone with concentric stars, but you could quite happily cut out circles and then cut out angels, Christmas trees or simple geometric shapes. If you go for a round version with a circle inside for the jam, they become known as Linzer Augen (“Linzer Eyes”).
I made these with quite a few tasty ingredients to get a really festive flavour, but not all of them quite traditional. While you can use almonds, I preferred to go with hazelnuts, as they add a great flavour to biscuit dough when baked. If you keep the skin on them before grinding, then you’ll get the typical brown flecks in the finished biscuits. I also used brown sugar to get a slight caramel flavour, and then flavoured everything with cinnamon, ground cloves, vanilla and orange zest. While it is usual to add just cinnamon and vanilla, I think the cloves and orange really do make the flavour very special. The clove flavour lingers on the tongue, while the zest perks everything up.
If there is something annoying about making Linzers, it is that the dough is on the soft side. This can be easily addressed by making sure it is properly chilled before getting into the rolling and cutting, so ideally you want to make the dough the night before, rather than doing it in the morning and clock-watching in anticipation of turning the oven on. You will, however, find that you are constantly taking pieces of dough from the fridge, and then returning scraps to the fridge to re-chill. However, don’t be tempted to skip this – the heat from you hands alone will soften the dough, and can turn it oily and unworkable. It is also worth doing a test bake before committing a whole tray of biscuits to the oven – if the test does not keep its shape, then pop the tray into the freezer to chill – and when you bake them, they should stay pretty much razor-sharp at the edges.
If you make these biscuits, it is worth knowing that they start of as very crisp. After a day or so, they will get softer and more cake-like in texture, so keep this in mind depending on how you like you bakes to turn out when you serve them. If you want to make them ahead of time, I recommend keeping them – without the jam – in an airtight container, and then baking them again briefly when you need them to get them back to their crispy best.
If you’re after a bit of variety, you can use different types of jam (like I did last year when making Swiss Spitzbuben). With the spices I used, I think plum jam (Victoria or damson) would be delicious, as would marmalade, or the traditional blackcurrant. The only think that you need to worry about is using jam that is sufficiently sharp and has a bit of a tang, to balance the sweetness of the biscuits.
So here we are at the two-thirds mark in this year’s Twelve Days of Baking (or Baking Madness, if you prefer). I hope you’ve enjoyed it so far.
To make Linzer Biscuits (makes around 40):
• 140g hazelnuts (skin on)
• 280g plain flour
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground cloves
• 1/4 teaspoon salt
• 225g unsalted butter
• 140g soft brown sugar
• 1 large egg
• 1 teaspoon vanilla extract
• zest of one small orange
• 150g raspberry jam
• icing sugar, to dust
1. Grind the hazelnuts until fine. Mix with the flour, salt, cinnamon and cloves and set aside.
2. In a large bowl, beat the butter and sugar until light and fluffy. Add the egg, vanilla and orange zest and mix well. Fold in the dry ingredients and mix well (the dough will be very soft). Wrap the dough in cling film and leave to chill for a couple of hours, or overnight.
3. Preheat the oven to 175°C (350°F). Line a baking tray with greaseproof paper. Take chunks of the chilled dough. Work briefly to soften it, then roll out the dough to 1/4 inch and cut shapes with a star or fluted cutter. Bake half the cookies until just lightly browned at the edges (10-12 minutes depending on size). In the meantime, remove the centres from the other half of the cookies with a smaller cutter, then bake those (they will need a little less time in the oven). Repeat until all the dough has been used, remembering that for every base, you need a top cookie.
4. Once the cookies are cooled, it’s time to assemble them. Put the jam in a saucepan. Heat until runny, then pass through a sieve (or use seedless jam). Allow to cool until thickened, then spoon a little jam onto the basis. Smooth with a spoon, then add the top layer. When all the cookies are done, dust lightly with icing sugar – any sugar that lands on the jam will dissolve, leaving perfect festive shapes.
Worth making? Yes! These are rich, delicious, and while they take a little time, they are fairly easy to make. You also get a large batch for little effort, and they store well in case of unexpected guests.
