Happy September! It seems like summer disappeared in the blink of an eye, but honestly I’m always happy to see fall arrive — the changing colors and warm spices signal my favorite time of the year. Plus, the cooler temperatures make me even more excited than normal to bake fresh loaves of sourdough bread. There’s something so comforting about the warmth of the oven and the aroma of fresh bread on a crisp fall day!

This einkorn and rye sourdough loaf is a new favorite around these parts. If you’ve never tried einkorn flour, you’re in for a treat. It has a wonderful nutty/grassy aroma and gives dough a silky smooth feel. Einkorn is relatively low in gluten, which can make it challenging to incorporate in large percentages. Here I’ve kept it to 20% — enough to impart its unique flavor without making the dough too unruly.

Baking this loaf was easier than ever using my new Copper Chef Wonder Cooker. Many home bakers like to bake their hearth style loaves in preheated dutch ovens, which trap steam and retain heat similar to professional steam-injected ovens. Because I tend to shape my loaves as batards (ovals), I usually have to use a more complicated setup create steam in my home oven. The Wonder Cooker, though, can function as a dutch oven; and its oblong shape and 9-quart capacity easily fits my standard 1.5 – 2 pound batards — hooray!

Another of the Wonder Cooker’s winning features is the ability to configure it so that the shallow pan is on the bottom — I simply have to slide the prepared loaf onto the preheated pan rather than worry about dropping it into a deep (and blazing hot) pot. I definitely see myself baking a lot more loaves in the Wonder Cooker — it’s so easy, and the results are top notch.

I’m happy to announce that Copper Chef is graciously offering a free Wonder Cooker to one of my readers! I’ve enjoyed this versatile cookware not only for baking bread but also frying donuts; and I’m looking forward to testing out more of its 14 cooking functions in the very near future.

Einkorn Rye Sourdough

Makes one large loaf

Ingredients:

• 150g AP flour (37.5%)
• 130g bread flour (32.5%)
• 80g whole einkorn flour (30%)
• 40g whole rye flour (10%)
• 70g 100% hydration ripe sourdough starter (17.5%)
• 320g water, divided (80%)
• 9g sea salt (2.25%)

Method:

1. Mix together the flours and water (reserve 50g for mixing later) and autolyse (rest) for 2-4 hours, covered with a tea towel.
2. Add the mature starter and about half the reserved water and mix until the starter is incorporated. Rest for 20 minutes.
3. Add the salt and pinch in. If the dough feels like it can handle it, add in the remaining reserved water and mix to combine. If you did a long autolyse, the dough should be decently strong at this point and you shouldn’t need to mix too much (maybe 1-2 minutes). If it feels weak, do a couple minutes of stretch and fold or slap and fold so the dough is moderately developed. It will continue to strengthen through bulk so it doesn’t need to be smooth at this point. Transfer the dough to a clean and lightly oiled container and cover with a clean tea towel.
4. Bulk ferment in a warm place, folding every half hour for the first 1-2 hours and hourly after that. Bulk fermentation is done when the dough has increased by 30-50%, you can see fermentation bubbles along the bottom and sides of the container, and the edges are domed where the dough meets the container. For me, with the dough kept around 74-76F, this took about 4.75 hours.
5. Transfer the dough to a lightly floured surface and gently preshape into a round. Let rest uncovered for 20-30 minutes.
   Prepare your basket (or other proofing vessel) by lining with a lint-free linen/cotton tea towel or lightly dusting with rice flour. Lightly flour your work surface and the rested round. Flip your preshaped round and shape as desired (boule or batard). Transfer to the prepared proofing container and cover with plastic. Proof at room temperature for 30 minutes, then refrigerate for 12-14 hours (or overnight).
6. An hour before baking, preheat your oven to 500F (550 if it goes that high). You can bake this loaf in a Wonder Cooker (which you should preheat with the oven, covered with the shallow side down), or use your preferred method of steaming. While the oven is preheating, I also like to uncover my loaf (i.e. remove the plastic, but keep it refrigerated). This dries out the surface a little which I find makes scoring easier.
7. When the oven is ready, invert your loaf onto a piece of parchment on a pizza peel. Score as desired, then transfer to the oven and immediately lower the temperature to 500F. If using a Wonder Cooker, carefully remove the preheated pan, remove the cover, and gently slide the scored loaf (still on the parchment) onto the shallow side of the pan. Place a few ice cubes around the edge of the pan (not touching the loaf — optional, but I think it provides an extra burst of steam) and immediately cover the loaf with the deep side of the pan and return to the oven.
8. Bake with steam (or covered) at 500F for 20 minutes. After 20 minutes, lower the heat to 450F, remove the cover and bake for another 20 minutes at 450F or until your desired doneness, rotating a couple times for even baking. When finished, the crust should be nicely browned and the loaf should sound hollow when tapped on the bottom.
9. Transfer to a wire rack and cool for at least an hour before cutting.
