Langdale Essence of rennet good/ or not

[Matthewcraig]

I received a Lakeland voucher as a Christmas gift, for you who aren't familiar with Lakeland its a shop that sells kitchen equipment and some supplies. I saw this bottle of vegetarian rennet and I was going to buy it till I noticed the 'essence' part, so has anyone ever used this rennet before, if so what kind of results did you have; also what is an 'essence of rennet'
