A deliciously simple recipe, perfect for a bumper rhubarb harvest and what better ingredient to add to the filling than custard! Both gluten free and dairy free plus no egg so this is vegan too. Never the prettiest of bakes but what it lacks in looks it makes up for in taste.
100gbutter or butter alternative (I use Flora plant butter)
50gcaster sugar
5tbspwatericed water or as cold as you can make it
For the custard filling
20gBirds custard powder[see notes for alternatives]
40gcaster sugar
150mldairy free milkor normal milk
For the rhubarb filling
200grhubarbchopped
50gcaster sugar
For the glaze
2tbspapricot jamor another pale jam
Instructions
To make the galette dough
In a large mixing bowl measure the flour, sugar and butter. Using your fingertips or a pastry blender (I use the latter as hands can be too hot), break the butter down into the flour and sugar to make breadcrumbs.
Add the iced water one tablespoon at a time to the crumble mixture. After each addition use a rounded knife (like a butter knife) to cut through the crumble in a figure of eight. This motion brings the crumble together gradually as you keep adding the water.
TOP TIP: you are not looking to blend this galette dough as you would pastry. Ideally you want it to be flecked with little lumps of butter.
Once the dough has come together and is speckled with butter, gently roll into a ball and pop into the fridge to chill while you prepare your fruit.
To prepare the custard filling
Add the custard powder and sugar to a small jug, mix with a little of the 'milk' and mix to a paste.
Top up with the remaining 'milk' and mix thoroughly to combine.
Pop into the microwave for 1 minute, remove and stir well as it continues to thicken. Set aside to cool.NOTE: this will be a very thick custard.
To prepare the rhubarb
Add the chopped rhubarb and sugar to a bowl and pop into the microwave with a plate over it to quickly steam the stems.[see notes for the tinned rhubarb version and hob stewed version]
To make the galette
Preheat the oven to 200°C | 180°C fan | 400°F | Gas 5
Remove the chilled dough from the fridge and place on a lightly dusted large sheet of baking paper. Roll out into a dinner plate sized circle. No need to worry about the circle being perfect.
TOP TIP: keep the rolling pin well floured. The little speckles of butter may stick to the pin otherwise.
Once the dough is rolled out and slid onto a baking tray, add the custard first then the prepared rhubarb to the centre of the dough with a decent margin, ideally you need to leave 1.5-2 inches of dough around the edges.
Now you can fold the edge of the dough in towards the middle of the galette. the ends won't meet and you will be left with a hole in the top of the galette exposing the rhubarb-filled centre.
For a finishing touch I brush the tops of the galette liberally with apricot jam to ensure it turns a beautiful golden colour when baking.
Pop into the oven for 35mins until golden brown.
Once cooked remove from the oven and serve immediately with cream, even more custard, ice cream or cool and eat at room temperature with cream.
Notes
Alternative Custard VersionAs Birds is a may contain for dairy, you may wish to use a ready made plant based custard, there are also other powdered custards on the market if you wish to use these (wholefoods do one).Tinned Rhubarb VersionSimply add the sugar to a tin/can of rhubarb and add this to the galette.Hob-Stewed Rhubarb VersionAdd the chopped rhubarb to a lidded saucepan as well as the sugar and place on the lid. Heat on a medium heat for 4-5mins to soften the rhubarb then pour into a bowl to cool. before building your galette.
