I've been doing some experiments with Diastatic Malted Barley Flour to see if it actually makes any difference with my bakes. The first test was with some
Sourdough loaves but I wanted to try them in something that does typically call for it... Pretzels!
If you're not sure what diastatic malted barley flour is, it's basically extremely finely crushed barley, husk and all. It's supposed to provide a boost of nutrients for the bread yeast and give a darker color in baking.
To test it with the pretzels, I did two batches with the same ingredients, only one had 1 tsp of diastatic malted barley flour added to it (which is what seems to be the recommended amount for the amount of flour I was using).
Honestly, there was zero difference visually between the two batches. They both browned the same, had a similar crumb structure, rose the same amount and browned on the bottom similarly. The main difference is the batch with the barley flour had a lot more "pretzel" flavor. I didn't notice the lack of pretzel flavor when trying the batch without the barley flour, but as soon as I tried the one with the barley flour, it was really apparent.
The ingredients for each batch were:
* 3 3/4 cups (~560g) bread flour
* 1/4 oz (about 2 tsp) instant yeast
* 2 tsp sea salt
* 1 1/4 cups (~315mL) water (110’F)
* 3 Tbsp unsalted butter, melted
* 1 tsp Diastatic Malted Barley Flour (for one batch)
* Pretzel or coarse sea salt for topping (optional)
Pretzel bath (I doubled the amount below so I could use a bigger pot):
* 4 1/4 cups water
* 3 Tbsp baking soda
