Grab a bowl and add the soft butter together with the quark and mix well. See that no bits are left and the mixture is smooth.
Clean, rinse the Onion and Garlic and chop fine, add them to the quark/butter mix.
Throw in the rest of the spices and salt to the combination and mix it well.
Garnish with red capsicum, pickled cucumbers and capers.
Notes
Use a cottage cheese rich in fats for the best results, avoid low-fat cottage cheese! If you can get cottage cheese from a farmer's market, that would be the best option. If you can get 20% fat fresh cottage cheese, such as the Slovakian bryndza sheep cheese, that would be the most suitable choice. Of course these are hard to get by, so 4% to 6% cottage cheese will have to do.
You can also use Mascarpone or other flavorless plain cream cheese variations.
In Eastern Europe sheep cream cheese is still very common, and it lends the Liptauer a certain special flavor.
