Colomba round 1

Results of my first round of Colomba testing.

I think that results were satisfactory, but I learned several things:

1. Recipe: Colomba is not the same as panettone. I used my current panettone recipe, and the results were almost too soft and airy; Colomba is a long, flat cake, and so it needs a bit of structural integrity to be physically stable. Make sure your recipe isn't extreme in any direction.

2. Baking: Don't put the pans on a baking sheet, as the bottoms will either be burned or not as done as the rest of the cake. Because of the shape, Colomba bakes in less time than panettone. There is a balance between baking slowly enough for optimal dextrin formation, and fast enough to achieve good oven spring. Baking on a preheated stone seems like the best option to achieve both.

3. Sugar: This is a sweet cake, with a lot of top crust area. Between the glaze, pearl sugar and powdered sugar, it can become too sweet. So, reduce the amount of pearl sugar to a dramatic sprinkle.

4. Skewers: Make sure you have long skewers ready that can be placed in pairs diagonally through the pans right after removing from the oven, and have a place to hang the cakes. 

Crumb:

 This was a nice crumb result, for me it is more attractive than Massari's Colomba, which is made "con metodo pandoro". I can appreciate this, as a pandoro version would have a sturdier crumb. I have had the Fiasconaro Colomba Pandorata, and don't prefer it. And so, I am working with panettone dough here.

It is a light crumb and very moist; baked in 35 minutes to 93-4C. The shape of Colomba makes it important to check internal temperature in the center of the cake.  

My paper pans are small, designed for 500g of dough. I scaled these cakes at 550g, but will go higher next time. This is more of a fashion thing.

Dough development:

My Lievito Madre was out of storage for four days, and was fed twice/day, with alternating warm/cool refreshments and also alternating water and free storage. (water for warm refreshments, free for longer, cool refreshments). I use a thermoelectric cooler for both.  I find that around day three, I usually begin to see much more dramatic rising of the LM, particularly during warm refreshment (expected). I go another day before using the LM for baking. 

I did two baking-day refreshments, 4 hours each, each one rose very well. This helps to "sweeten" the LM just prior to using it to bake.

My first impasto was made with Pasini panettone flour, fermented at 22C for 10.5 hours. The final pH was 5.01. 

My second impasto was made with King Arthur Galahad flour because of this nice high pH, no worries about gluten damage in the dough. This was done to get the softest crumb, and indeed the crumb was very soft. Dough at the end of second impasto was extremely extensible and handled well.

For the next test, I will use technical flour for the second impasto as well. (It remains to be seen whether baking on a hot stone will offset the tenderness of the crumb)

Final rise was 4.5 hours at 28C in the Brod & Taylor proofing box. Glazed, pearl sugar, whole almonds and powdered sugar applied just before baking.

Overall, this was a good test and it's always nice to eat the results!
