Note about the Ingredients For this Blackberry Tart Recipe
- You can use fresh or frozen blackberries to prepare the blackberry filling.
- If you can, choose fresh blackberries for decoration. Frozen berries tend to lose their texture.
- A diplomat cream is a vanilla pastry cream with gelatine. When it is set, we add whipped cream. It brings a light texture.
- Check your gelatine strength. More details just below.
Not all gelatines are equal
I use gelatine powder, 200 bloom, for the Diplomat Cream on the top of the Blackberry Tart. Make sure to use the same bloom; otherwise, adapt the quantity.
The bloom of the gelatine is its “strength.” The higher bloom, the stronger the gelatine is. So if you use gelatine with a lower bloom, you need to increase the amount. If you use gelatine with a higher bloom, you need to decrease the amount.
How to adjust the quantity of gelatine?
- For my recipe, I use 4g of gelatine powder, with a strength of 200 Bloom. Let’s say, you have gelatine with 250 Bloom.
200/250 = 0.8 This is your multiplying factor
4g x 0.8 = 3.2g This is the amount of gelatine, 250 Bloom, you need to use to obtain the same texture as me.
- Here, another example with a lower strength, let’s say 150 Bloom.
200/150 = 1.33 This is your multiplying factor
4g x 1.33 = 5.3g This is the amount of gelatine, 150 Bloom, you need to use to obtain the same texture as me.
Note: I use a kitchen scale with readabilities of 0.01g to get precise weighing.
Note 2: If you prefer to use gelatine leaves, for this recipe you need 2 Gold (=200 Bloom) gelatine leaves. Ensure each leaf is 2grs.
Some brands refer to grade to qualify the strength of gelatine leaves instead of using bloom:
Bronze is 125 Bloom, Silver is 160 Bloom, Gold is 200 Bloom and Platinum is 250 Bloom. The weigh of one leaf may varie.
How to make the Blackberry Tart?
Here is a summary of each step:
- Start with the Sweet pastry shell – need to chill for 2 hours or, best overnight.
- Then, start the Diplomat Cream. A Diplomat cream is a vanilla pastry cream with gelatine, then when it set, we add whipped cream. I follow my vanilla pastry cream recipe. I adjust the quantity for this recipe. Please check my vanilla pastry cream blogpost. It’s full of tips to prepare it.
- Next, the blackberry pie filling – need to chill for 1 hour at least. I use my favorite raspberry filling recipe and replace the berries with the blackberries.
- When you preheat the oven to prebake the tart shell, you can prepare the almond cream.
- Whip the heavy cream to finish the Diplomat Cream when ready to assemble the Blackberry Tart.
