For the Baroque spice flavouring, what separates this from modern rosół:
- Generous pinch of saffron approximately ½ tsp, steeped in 2 tbsp of warm water for 10 minutes — the Compendium specifies saffron throughout. It gives the finished broth a warm golden colour and a floral complexity that plain broth does not have
- Juice of 1 lime freshly squeezed — lime is specifically documented in the Compendium as a standard Polish broth flavouring of the period
- 2 cm piece of fresh ginger root finely grated — ginger appears repeatedly in the Compendium and reflects the importance of spice in 17th century Polish court cooking
