I have Linseed & ground almonds, with almond milk. You can get a mix of linseed and ground brasil nuts, which is really nice. I add a bit of sweetener, 1 min 20 in the microwave, jobs-a-goodun!
I have flaked almonds and double cream, sometimes adding some seeds and other nuts. Stopped using almond milk as it is full of chemicals (a processed food) whereas cream is natural and therefore healthier (in my opinion).
The closest to UK cream is proper crème fraîche d’isigny. The milk from isigny (near Caen) tastes like British milk too. I lived in that region for some years
