Dr. Oetker Taartina Clear (cake jelly) 60g (5x12g) Taartina brings a beautiful shine over fruits and is very easy to cut. 1 sachet of taartina is perfect for 200-250 ml of water or fruit juice (200 ml for a slightly thicker and firm jelly). About 15-20 minutes after applying the jelly to the pastry, the pastry is ready to be cut.
