Zest a lemon and then juice both of them. Keep the zest for later.
2 lemons
Combine the lemon juice & caster sugar in a jug.
4 tbsp caster sugar
In a small pan warm the plant butter, golden caster sugar, oats and chopped ginger. Be careful not to burn the sugar, you want a nice caramel coloured mixture.
6 tbsp oats (oatmeal or rolled oats), 2 tsp plant butter, 2 tbsp golden caster sugar, 2-3 stem ginger pieces
Place a couple of tablespoons of the oat mix into a small cake ring on a plate and leave to cool.
Add oat cream to the lemon & sugar mix. Then whip until light and fluffy or use a nitrous cream charger.
250 ml Oatly Whippable Creamy Oat
Spoon the posset on top of the ginger base and top with lemon zest. Carefully remove the cake rings and serve.
Notes
I use a nitrous cream charger to make the posset, it takes less than 10 seconds to whip it to perfection. You really can't tell that the posset is dairy-free!
