Where can I buy rennet and how quickly does it work?Pretty much as it says in the subject, Where can I buy rennet and how quickly does it work? but a bit of context might help.
I'm giving some students a lesson on uses of enzymes and showing rennet in milk would b a good example if it can produce a visible effect within 30 minutes or so for a classroom demo. It doesn't need to produce a usable cheese in that time just a visible effect. Is that possible? or do I have to get all Blue Peter and say "Here's one I made earlier". And where do I buy rennet, preferable animal rennet and not vegetarian.

timing depends on temp
iirc around 35c will be about right for demonstration purposes (over 40c is likely to denature the enzyme) but i dought you will see much effect in a lesson length of time
for making junket or cheese tis usually done cooler to avoid pathogens being happy
in a cool room a junket takes overnight to set
if you disturb the set milk it will break up into curds and whey(as in cheese making) so the blue peter hioime might require a bit of planning
re supply, online is probably your best option as home cheese making isnt common and junket seems to have died out with the victorian cornish iirc it was stocked by a few pre supermarket grocers and some larger chemists shops as late as the early 1970's.a local cheese maker might be able to help.
slight overkill for one lesson but they do stock natural rennet and it will keep reasonably well in a fridge.
having looked online ,since when was cheese vegetarian? but i spose vegetable rennet still curdles milk.

My Mum made junket up to the late 1960s.
I hated it.
She certainly wasn't Victorian.

Many of the shops here in Devon sell it. It takes a couple of hours or so to set depending on temperature. You will get an observable, though not measurable result in 1/2 hour, especially if you use a water bath or something.
Shall I post you some?
