Oh yeah, it’s that time of the week when we’re talking GBBO. And I’ve got a good one for the bakers this week, Mary Berry’s Choux Buns aka Religieuse. Talk about DELICIOUS!

Mary Berry's Religieuse

Religieuse. What the what? 

I know I hear you on that one, Religieuse, what in the world? I’ve been just calling them Nun Buns in my head, which sounds bad, I know.

Religieuse are choux buns (or cream puffs,) filled with pastry cream, dipped in ganache, stacked on top of each other, and piped round with whipped cream. 

I THOUGHT I knew what fiddly was when I made the Floating Islands Dessert a few weeks back. That has nothing on Religieuse. These are the fiddliest choux buns I’m ever making.


Mary Berry's Choux Buns

The name Religieuse comes from the fact that they do indeed look like little nuns when made properly. Dark chocolate ganache, white piped whipped cream, these plump choux buns are fun.

And that’s the KEY PHRASE right there “when made properly.”

Let me tell you about my adventures making these. Don’t worry I’ll keep it short and sweet because EVERY SINGLE PART of making them was done wrong.

I have lessons on what NOT TO DO. 

If anyone saw in the kitchen they would have been ashamed of me, I WAS! I felt like I’d never baked anything in my life.

So instead of me telling you how to do, I’m sharing how not to do it. 

How to Make Mary Berry’s Religieuse Choux Buns

First up Choux Buns. In the end, I skipped Mary Berry’s Choux Buns recipe because, well you’ll read about it right now. Let’s just say I could not get them to work, and it wasn’t for lack of trying.

I followed Mary Berry’s recipe on BBC Foods which lists every ingredient, except water. Which it CALLS for in the directions but because it wasn’t listed, I didn’t have it on the radar. Yes, I should slow down and read all of the directions but I was speeding through this because I KNEW WHAT I WAS DOING. 

Obviously I didn’t because I made them TWICE before I figured out I was doing something wrong. And after reading the recipe I realized I left out the water. Make them one more time and I still screwed them up because they didn’t rise. Once more was what I needed. In the end, I went with halving my old choux bun stand-by. SUCCESS, finally.

Mixing Pastry Cream for Choux Buns

Let’s talk pastry cream. The recipe calls for whipping the eggs with the sugar. NOT A PROBLEM I got this. Except I was so good at this I dropped an eggshell in the stand mixer while dropping in egg yolks and had to start again. But once I got them in right, they were pale and creamy and perfect. 

I was also heating the milk as well. As soon as it came to a boil I took it off the heat and let it cool while I whisked the flour and starch in the eggs. Be sure to scrape down the sides of the mixing bowl, it’s important because the flour and corn starch like to stick to it.

Pastry Cream; Mistakes Were Made

I poured to cooled milk in the eggs, with the mixer on high. DO NOT DO THIS. Just gently mix them in if you’re using a stand mixer, use the lowest setting. 

What I managed to do was whip the hell out of the milk and eggs and create a 4-inch froth of milky eggs on top of the liquid. 

Pushing on, I poured it back where it came from, which happened to be a small saucepan. The frothy mess came right up to the rim. 

Luckily I managed to remember to whisk whisk whisk over high heat. But then walked over to check the directions and came back to lumpy cream.

I was so over it by then I just kept whisking and let the cream get thick. I was putting it through a sieve anyway so a few bits of scrambled eggs weren’t going to stop me. 

The sieve worked fine and the cream tasted fine but it took way too long to knock down the foamy mess.

Somehow I pulled off the ganache pretty painlessly. Usually, it’s grainy or dull but I like it. It looks pretty good, on Mary Berry’s Religieuse don’t you think?

  7. when the dough has cooled, add about 1/4 of the eggs and beat it in with a wooden, repeat the addition and beating in with the rest of the eggs
  8. use a piping bag with 1/2 tip to pipe 8 two-inch circles and 8 one-inch circles
  9. bake in a 400˚ oven for 30 minutes
  10. when they're done pull them off the baking sheet and use a knife to make a hole in the side to let the steam out, they can cool while you prep everything else

  16. once they're combined pour all of it back in the saucepan
  17. whisk the mixture over medium-low heat, don't stop whisking or you'll get lumps or scorch it or both
  18. when it has thickened up, put it through a sieve to remove all the lumps
  19. lay plastic wrap over the surface and cool on the counter then transfer to the refrigerator
