Nielsen-Massey Food Flavour - 60ml Coffee Extract 5 "Ratio of essence to use" Mrs JULIA MUSSON 18 October 2013 I have just purchased this essence and was looking forward to making some mini coffee/chocolate muffins however the usage given is so vague: 1/2 tsp for subtle flavour to 1.5 tsp for strong flavour.......but to what measurements is that? It forced me to give a rating.....I am assuming it will be great! Thank you A note from the team Thanks for placing your review. The recommended usage on the bottle is a guideline depending on the mix you're wanting to flavor. We do hope you achieve the results you're wanting and enjoy the results.
