Do you remember Attempt #1 at Devonshire Junket? I failed miserably. But I shall not be defeated! Upon careful reading of the directions, I discovered that it doesn't work if you use canned milk. Which I was, oddly enough. It was on sale. Please do not judge me.
From A New System of Domestic Cookery, Formed Upon Principles of Economy, and Adapted to the Use of Private Families .
Put warm milk into a bowl; turn it with rennet; then put some scalded cream, sugar, and cinnamon, on the top, without breaking the curd.
Not actually very hard to find at the grocery store.
More Helpful Directions:
2 cups milk
1 Junket Rennet tablet
1 T. cold water
1. Have 4 individual dessert dishes ready.
2. Heat milk to lukewarm while stirring (110 degrees F.). Dissolve rennet tablet in water by crushing. Add to warm milk and stir for a FEW SECONDS ONLY. Pour at once, while still liquid, into dessert dishes.
3. Let stand UNDISTURBED for 10 minutes. Chill.
4. Drizzle cream over and sprinkle with brown sugar and cinnamon. Don't stir it in, leave it alone and eat it by spoonfuls. The more the curd is broken, the more the structure breaks down and releases whey, looking unsightly.
Verdict: This is totally easy! Really, about the same difficulty level as Jello. As long as you don't use canned milk. And it is pretty delicious, too! It is sort of like a cross between Jello and custard. I did this a couple times more, once with vanilla mixed into the milk, which was delicious, and and once with orange flavoring. And yet, my favorite is still brown sugar and cream. Yum. An accurate flavoring for the time period would be rosewater or orange blossom water*, which I think would be delightful, and intend to try.
If you're having a Regency party, or just in the mood for a unique dessert, you should try this. It is super easy and unique.
*Which, I have discovered, can be found near the drink mixers at the grocery store.
