Sesame Sunflower Porridge Sourdough + The Pistachio Brioche I Promised


Hey Reader!

It finally feels like things are starting to move again in the kitchen. After a busy stretch and a bit of a pause from the book tour, I’ve been back baking and testing new ideas.

This week, I’m sharing a sesame and sunflower porridge sourdough that turned out incredible. The porridge method is one of my favourite ways to add flavour and texture to bread.

I also have some exciting news: my publisher just let me know they’re ordering another print run of Bread, Etc. — which means we’re now going into our third printing. That’s honestly huge and means the book is selling better than expected. Thank you to everyone who has bought a copy, baked from it, and shared it with friends.

If you already have the book and have been enjoying it, leaving a quick 5-star review wherever you bought it (Amazon, Indigo, etc.) really goes a long way for me and helps more bakers discover it. I appreciate it more than you know.

And yes… I also finally wrote out the pistachio brioche beesting recipe I’ve been teasing out.

If You’re New Here, Hi 👋

I’ve had a big wave of new readers lately, so a proper intro feels overdue.

I’m Matthew, a classically trained chef and baker with over 20 years in professional kitchens, bakeries, and classrooms.

I studied French cuisine early in my career and went on to cook and bake around the world, working in Japan, Denmark, NYC, Italy, and even on Vancouver Island. I spent five years at the Four Seasons Toronto and worked alongside Chef Daniel Boulud as a sous chef (opened two restaurants under his mentorship). I’ve trained with master bakers in Germany, studied (and taught) at world-renowned baking institutions, and represented Canada multiple times at Terra Madre in Italy.

For years, I was a Baking and Pastry Arts professor at Centennial College, where I taught and coordinated the baking management program.

Today, I’m a private chef for an ultra-high-net-worth family (don’t ask, I won’t tell you 😂), while continuing to teach, write, and bake.

I run:

  • A blog at matthewjamesduffy.com
  • A YouTube channel with 100,000+ subscribers
  • A micro bakery with my wife
  • Digital baking courses on rye, baguettes, panettone, sourdough, and sourdough pizza (all the courses are linked at the bottom of this email)
  • And I wrote Bread, Etc. — now a national bestseller (which still feels surreal)

Everything I do revolves around one idea:

Bake like a chef. At home.

If you’re looking to seriously level up your skills this spring, I’ll be running an Easter sale on my digital courses soon. It’s the best time to jump in.

And if you’re just here for free recipes and to get better at baking one bake at a time, you’re exactly where you should be.


Pistachio Brioche with Diplomat Cream AKA Pistachio Beesting 🐝

Alright. Here it is. I’ve had a huge number of messages about this one, so I wanted to give it the proper write-up.

The base is a 300g brioche round, rolled out and topped with pistachio caramel before baking. Once cooled, it’s sliced in half and filled generously with diplomat cream.

The combination is what makes it special.

Buttery, fermented brioche.
Nutty pistachio caramel baked into the top.
Light, silky diplomat cream inside.

It’s inspired by a classic bee sting cake, but built on brioche instead of sponge.

For the diplomat cream, I used Jeffrey Hamelman’s method as a base, and the pistachio caramel was inspired by his approach as well. The brioche itself is my formula from Bread, Etc., but you can use any brioche you trust.

This isn’t an everyday bake.

This is a showstopper, and please read the full recipe before you start, as this one is an advanced recipe.


Oat Porridge Sourdough (With Roasted Sesame & Sunflower) 🌻

This week I made an oat porridge sourdough that absolutely crushed.

The base porridge was cooked with honey, then finished with butter and roasted sesame + sunflower seeds that I blitzed in the blender so they weren’t whole. That little move makes a huge difference. You get all the flavour and richness without breaking the crumb structure.

It was nutty. Slightly sweet. Deeply toasty. Super moist. And it reminded me why I love the porridge method so much. Once you understand the base idea, the combinations are endless.

I usually run porridge at about 30–35% of total flour weight. From there, you can swap grains, sweeteners, fats, seeds, even fold in fruit or spices.

A couple of important notes if you try this:

• Cook the porridge quite dry. It should be thick and gelatinous, not loose.
• You’ll always have slightly variable porridge weight because of evaporation. That’s normal.
• Instant oats cook faster and often need less water. Regular oats take longer and may need more.
• Always cook it dry enough that it holds its shape when cooled.

The porridge needs structure before it goes into the dough.

This one isn’t on the blog yet, but I’ve included the full Excel formula below if you want to bake it exactly as I did.

I put together a full guide and video that breaks down some tips on how to work with high-hydration sourdough, and it’s not just about adding more water.

High hydration is really about:

• Fermentation
• Flour strength
• Mixing strategy
• Dough management

Here are a few quick tips that make a massive difference:

1. Know your flour.
Weaker flours and softer grains absorb less water. Strong bread flour can handle more. Whole grains can take even more. Hydration isn’t a fixed number — it’s flour dependent.

2. Manage fermentation first.
A high-hydration dough that’s under-fermented will feel slack and impossible to shape. Often, the issue isn’t water — it’s time and temperature.

3. Hold back water and add it later (bassinage).
Develop strength first, then slowly add reserved water. You can always add water. You can’t take it away.

4. Use wet hands and folds to build structure.
Wet dough needs gentle strength building. Regular folds during bulk fermentation make shaping much easier later.

5. Cold ferment.
A proper cold proof firms up the dough, improves flavour, and makes scoring way easier.

If you’ve ever wondered why your “high hydration” loaf spreads instead of springs — this guide will help.


This week in the micro bakery 🕺Back in the Test Kitchen

We’re finally back to developing new recipes.

After a bit of a hiatus thanks to the intense book tour (still wild to say that), I’m back in the kitchen working on the website again, and it feels really good.

This week I played around with:

• Sourdough crepes
• Buckwheat crepes
• A new bun formula
• Hoagie / bánh mì rolls
• And a soft milk bread baked in a rabbit-shaped mould for my daughters (yes, I bought a bunny bread mould and yes, it was worth it 😂)

It feels like spring testing mode is officially on.

If there are specific breads, techniques, or recipes you’d love to see on the blog or in this newsletter, hit reply and let me know.

I can’t make everything… but I genuinely love the process of developing new formulas and sharing them with you.

Your ideas actually shape what gets baked.

Happy Baking,

MJD

Hey Reader! This week was a fun one. I had the chance to be part of a chocolate collab dinner, which pushed me a bit creatively. I ended up making a few different loaves for the menu: Triple chocolate sourdough Cocoa nib sourdough Chocolate sourdough with cranberry and cocoa nut Brioche It’s not every day you’re putting chocolate into bread like that, but it actually worked really well—especially paired with some of the dishes on the menu. If you’re curious, there’s a full write-up by Adam...

Hot Cross Buns

Hey Reader! For the first time since November 2023, I missed my usual Friday morning newsletter. I’ve been sending this email consistently every single week, so it honestly felt a bit strange to realize I had completely forgotten. We had just returned from a quick family trip to California to visit relatives and a little time at Disneyland. The jet lag hit all of us harder than expected, and somewhere between getting home, unpacking, and trying to get back into routine… it simply slipped my...
