Macadamia in Sourdough — How to Use Macadamia Nuts in Bread

Choose raw or dry-roasted macadamias without added salt or oil so you control flavor and fermentation. For best distribution and easier mixing, roughly chop or pulse in a food processor to pieces about 5–10 mm. Toasting intensifies flavor but also reduces available surface lipids; toast quickly at 160–170°C (320–338°F) for 6–8 minutes until fragrant, cooling completely before use. To hydrate for a softer, less crunchy inclusion, soak chopped macadamias in a small amount of water, milk, or even a liqueur for 20–60 minutes, drain well and pat dry — retain soaking liquid if you want to count it toward dough hydration. Weigh macadamias on a kitchen scale for consistent results [1].

Macadamias are high in fat (~70%) and low in water compared to flour; added fats disrupt gluten network formation and can reduce dough strength and extensibility if used in large amounts. Expect slightly tighter crumb and slower gas retention when nuts exceed ~10–15% of total flour weight. The oil from macadamias can lubricate dough making it feel softer and stickier; counteract by maintaining proper gluten development through longer autolyse, stretch-and-folds, or stronger knead. Because macadamias aren't hygroscopic like flour, scoring hydration solely by flour weight undervalues the water needs if you use soaked nuts — include the soak water in your hydration calculations if retained [1][2].

Typical approach for 1 loaf (750–900 g dough): use macadamias at 8–15% of flour weight (example: 500 g flour → 40–75 g macadamia). Additions timing: • For crunchy pieces add during the final set of stretch-and-folds (usually 60–90 minutes after mixing) to avoid over-distributing oil into the dough. • For softer, integrated pieces add after autolyse but before bulk fermentation begins so they hydrate slightly and meld with the crumb. Use a dough scraper to turn and fold the dough when incorporating nuts to avoid excessive handling. Example schedule: mix flour, water, and starter; autolyse 30–60 min; mix salt and perform initial folds; after 1–2 sets of folds incorporate macadamias on the next fold; continue 2–4 more folds during bulk fermentation [1][2].

Shape gently to preserve inclusions: tight shaping can cause nuts to concentrate near the surface. Use a banneton or lightly floured linen for proofing to support the dough. Score to control oven spring; oil from macadamias may cause slightly reduced oven spring, so aim for effective steam by using a Dutch oven or cast iron pot or a cloche to trap moisture. Bake until internal temperature reaches 96–99°C (205–210°F) using an instant-read thermometer for consistent doneness. Parchment can help transfer a nutty loaf into a hot pot — have parchment paper ready. Expect a slightly richer crust color due to nut oils; cool fully before slicing to avoid gummy crumb [1][2].

Macadamia-containing loaves stay softer and may last a day or two longer than lean breads because fats slow staling, but the fats can go rancid faster than bread starches if exposed to air and heat. Store wrapped at room temperature for 2–3 days; for longer storage, freeze slices in airtight bags. If you plan to keep a portion of macadamias for future bakes, store raw nuts in the refrigerator or freezer to preserve freshness and avoid off-flavors [1].
