I made a chocolate ice cream recipe from The Kentucky Housewife cookbook, published in 1839. I did a bit of research on 18th and 19th century ice creams before I settled on this particular recipe. It's not completely authentic though I followed the receipt, but chocolate as we know it, be it bar chocolate or even processed cocoa is not the same product as it was in earlier times. Also, not having a sorbetiere, or even a manual ice cream maker, I ended up using my electric ice cream maker, which I will admit is very enjoyable to use.
Several cookery books have very specific instructions on how to make ice cream, but no, or few actual recipes. However the 1830 The Cooks Dictionary tells us not only how to make ice cream, but how to adjust recipes for "creams" to make ice cream, as well as having a number of different ice cream recipes. Most of the cookbooks have recipes for creams, which are custardy, mousse, pudding-like desserts. Apparently you just make the cream recipe a little less thick and then use it to make ice cream.
Because I didn't have enough cocoa on hand, and wasn't going to town for a few days, I used baker's chocolate. I know a number of the recipes call for mixing the chocolate with water, which would be a cocoa product, not bar chocolate as it would seize. I grated it and it made this lovely pile of soft, tiny chocolate flakes which melted easily into the milk mixture. Because the chocolate was semi-sweet, I cut the amount of sugar in the ice cream as well. I used a 10% cream mixture because we only had 1% milk and even our whole milk doesn't have enough fat content to qualify for "rich, sweet milk". Also because a litre of that mixture was cheaper than purchasing a litre of whole milk and a container of double or whipping cream. I also only used 4 eggs because my chooks are laying very large eggs, with large yolks. I followed the directions, melting the chocolate in the milk mixture and then letting it cool a bit. Then I added the yolks and the sugar and brought the mixture up to just a boil. This is pretty important as it cooks the eggs. I stirred it constantly. When the custard had boiled just a tad, I removed it from the heat. I let it cool a bit, then transferred it to a bowl, covered it with plastic wrap and put it into the fridge overnight. While this step is obviously modern, it is one of the procedures that is suggested in the instructions of the modern ice cream maker.
The next morning, I put the now fairly thick and cold custard into the ice cream maker and in about 15 minutes the ice cream was quite thick. The instructions say to freeze twice. In reality this means to pack the ice cream into a mould and re-freeze by setting it in the ice and salt mixture. I didn't have a suitable mould, so instead I packed it into a lined loaf pan and set it into the freezer. This second freezing allows the semi-soft frozen ice cream to harden up nicely.
The ice cream scooped up nicely. It was so creamy and rich. It had a great mouth feel and felt very decadent. I would use less chocolate next time, and try it with a mixture of cocoa and chocolate, which might replicate the actual period chocolate available.
Would I make this again? Indeed. It was well worth the effort. There is a recipe for peach ice cream in this book and there are tinned peaches left in my cupboard. That will be the next recipe to try.
