So the liquid rennet bottle says the rennet must be diluted 20:1 in cool non-chlorinated water. Then it says 1/2 tsp sets 2 gallons of milk in about 45 minutes. Is that 1/2 tsp DILUTED or full strength? I've e-mailed the folks who sold it to me but haven't heard back yet. If it's diluted rennet, then I guess I need to get an eyedropper! Of course, the good news then would be I'll not have to order rennet again this decade.
