“Rochefort 10” Ice Cream and Strawberry Ice Cream

This Rochefort 10 ice cream is based on a recipe I found on the Belgian foodblog Hot Cuisine de Pierre. It’s a very nice beer and the idea of making ice cream with it is sheer genius…

Rochefort is a Belgian brewery is associated with the Notre-Dame de Saint-Rémy Abbey near Rochefort. Monks have been brewing beer since 1595, providing much of the income for the monastery. Rochefort 10 is one of three “trappist” beers and this intense dark brown beer is also their heaviest at 11.3% ABV.

What worked and what didn’t: 
I used the strawberry ice cream recipe from my Solis Ice Cream machine’s instruction manual and we also tried some extra molecular elements: chocolate and fruit spaghetti. However, they took ages to make and the result – the stuff hiding under the blueberries and mango bits – frankly was rather underwhelming so I won’t bother you with those.

The HCP recipe itself already really worked as it called for 2 bottles of Rochefort 10 to only discover halfway that one of those is meant to quench the cook’s thirst! And again to discover at the end that the cook wasn’t supposed to drink that entire beer as you needed to put in a couple of tablespoons of beer when the ice was almost finished churning. Fun stuff and a great excuse to open another bottle….

The ice creams were very good: The Rochefort 10 was nice and creamy and had a real subtle flavour that conveyed all the characteristics of the beer, so a job well done. What didn’t work was the decision not to eat all the Rochefort 10 ice cream in one go. I put some back in the freezer only to find out a couple of weeks later that the ice cream actually had turned stale!! 😲 That was a real bummer…

The Strawberry ice was nice too. A bit sweet, but the added lemon juice did give it a slight lift. Straining strawberry pulp sounds easier than it is as all the seeds kept clogged the sieve. So only sieve small quantities at the time and scrape out the seeds every go!

Recipe accuracy:
The recipes are accurate and you’ll get about 1 liter of ice cream each.

Suggested tweaks:
As sugar is an important factor of the consistency of ice cream (especially when adding other liquids), don’t cut back on the sugar in the custard mix. You can cut down a bit on the sugar added to the fruit if the ice cream turned out too sweet for your liking.

If you don’t prefer a smooth strawberry ice cream, just blitz and sieve half of the strawberries, sugar and lemon juice and mash the remaining strawberries with a fork and let it infuse overnight with the remaining sugar and lemon juice. When mixing the sieved strawberries with the custard, also add the excess liquid from the mashed strawberries. You can then mix in the mashed bits of strawberry close to the end of the churning cycle.

Verdict: 9/10; Will definitely be made again

The recipes:
