Dr. Oetker small flavour tubes are very easy to open and close thanks to the convenient fastener. Simply snap the top sideways and start refining pastries and desserts with the most delicious Dr. Oetker flavours. The well-known Dr. Oetker rum flavouring brings a touch of rum in any kind of pastry and desserts. One small bottle of flavour is sufficient for 500 g of flour or 500 ml of liquid. The flavour can be poured in (small) drops to vary the taste's strength.
