Elderberry Tart with Cassis
Elderberry Tart makes the most of this delicious foraged fruit. Elderberries & a cassis flavoured custard fill this butter pastry shell – Yum!

There’s an abundance of elderberries out there ready to be picked and preserved, the beauty of elderberries is that you don’t need to live in the countryside, you’ll find them in parks, gardens and alongside footpaths in the city too.

Elderberries are best not eaten raw, they can give some people a bad tum but if you’ve ever eaten one straight from the bush you’ll know they are rather tart. Tasting a bit like a blackberry but more sour and they have a slightly earthy taste. See my Harvesting Elderberries post for more details on what to look for when picking and more recipes with elderberries to make the most of your foraged fruit.

Tart aux Myrtilles is the inspiration for my Elderberry Tart. I’ve used a rich butter pastry and used a small amount of custard flavoured with Creme de Cassis as a base for the elderberries for my version of this much loved tart. It truly is delicious, the elderberries adding just the right amount of tartness and fruitiness and if you’re like us you won’t be able to stop at just one slice. Serve cold ( if you can wait that long) with a dollop of creme fraiche or Homemade Clotted Cream.

If you like elderberries, why not try my Elderberry Jelly with Port? – this fruity seedless jam is delicious on toast or a scone and is equally good with cooked or cold meats as it pairs perfectly with beef, pork, lamb and poultry. Simply add the jelly to your gravy or jus as you would when using redcurrant jelly.


Elderberry Tart
Equipment
- 1 x 23 cm (9 inch) flan/tart tin
Ingredients
Pastry:
- 200 g plain flour
- A pinch of salt
- 100 g chilled butter, cut into small cubes 3½ oz
- 4 tablespoons icing sugar
- 1 egg yolk freeze the white for later
- Approximately 2 tablespoons water
Filling:
- 2 eggs
- 115 g caster sugar plus 2 tablespoons for sprinkling
- 175 ml double cream
- 50 g plain flour
- 2 tablespoons creme de cassis
- 500 g cleaned ripe elderberries with stalks removed 1 lb
Instructions
Make the pastry
- Sieve the flour and salt into the mixing bowl of the stand mixer. Add cubes of butter and mix on slow with a paddle attachment until the mixture resembles fine breadcrumbs. Add the icing sugar and briefly mix.
- Briefly whisk egg yolk and water in a small bowl before adding to the pastry mix. Mix on slow until the pastry forms. This shouldn’t take long at all, less than a minute – you don’t want to overwork the pastry.
- Wrap the pastry in cling film and leave in the fridge for 30 minutes until firm but not hard.
- Grease 1 x 23 cm ( 9 inch ) loose bottomed flan tin.
- Roll out your pastry to about the thickness of a £1 coin ( ⅛ inch ) making sure the pastry circle is large enough for the diameter of your flan tin plus twice its depth.
- Carefully line your tin with your pastry before popping in the fridge for at least 15 minutes.
- Preheat oven to 200℃ / 180℃ Fan / 400℉ / Gas Mark 6.
Prepare the filling:
- Whisk together the eggs, sugar, cream, plain flour and creme de cassis until smooth.
- Place the elderberries in the pastry case and pour over the creamy filling.
- Sprinkle with the remaining 2 tablespoons of caster sugar before placing in the oven for 35 to 40 minutes until baked.

Thanks for the great info about elderberry Sarah, had no idea, now I know not to eat them raw. The tart looks so good that I don’t know whether I’ll be able to wait for it to cool down.
I’ve been wondering what to make with elderberries lately, and this is just perfect. Cassis is one of my all-time favorites too!
What a fun way to enjoy elderberries! I love your use of flavors in this recipe as well! YUM!
It’s been really hard to find Elderberry gummies right now, which are good for your immune system. But, that said, I will look for fresh elderberries to make this yummy tart recipe! I’m sure it’s got some health benefits too!
This looks so fresh and delicious! Can’t wait to try this recipe!
Please help! The ingredients for the filling include 4 oz sugar, but the instructions for making the filling doesn’t discuss those 4 ounces. Am I to blend the sugar with all of the other custard ingredients? I’m in the process of making this tart. Live in the US and found some elderberries in the Adirondack mountains yesterday.
Hi Janet, yes you are to blend the sugar with the custard ingredients. I realise this reply is probably too late but I hope you got on ok. Recipe is amended.
This looks super delicious. I’ve never made a tart using elderberry before, I will have to try.
I don’t think I have ever seen elderberries here in the US, so this recipe intrigues me. These berries look like the pack some flavor.
Oh my gosh this pie. This looks crazy delicious and love that you use elderberries in there, such a under used fruit. YUMMMMMMM.
