When you have a baking fail, the first place to start is calculate and analyze the baker’s percentages.
But when volume measurements are used, it’s impossible to calculate the baker’s percentages. The best that can be done is guesstimates of the weights. From the guesstimates, I calculated these baker’s percentages.
What the baker’s percentages show is excessive liquid and fat in this formula.
Water: While water is required for gluten, excessive water will destroy dough. A high hydration dough has 70% hydration (water). This formula has 208%. Now pate a choux is an outlier in that it is twice cooked, the first cooking on the stovetop evaporates water. So a choux dough can start with more water than the average dough. But still, 208% extraordinary high—especially with the bleached white flour which is a moderate level protein flour.
Butter: fat inhibits gluten development. The fat is on the higher side. That in of itself would not be an issue if not for the extraordinary amount of water. There is no way to create a strong dough with such high percentages of both water and fat—not to mention a bleached white flour.
Cheese: The cheese to flour ratio is significantly higher than it should be at 170%. I mentioned in an earlier post the ratio of cheese to flour should be about 125% - 130% for most cheeses. Cheese is both fat and weight. When you have a weak dough and the added weight of the extra cheese, the dough collapses. Multiply the weight of the flour by 1.25 - 1.30 to determine the weight of the cheese to use in the dough.
Assuming eggs out of the shell are 50g each, the egg amount of egg used is in the wheelhouse.
Salt is slightly higher at 2.5% than the standard of 1.5%. The salt should be adjusted for the type of cheese used—some cheeses are saltier than others.
Frankly, the amount of work to fix the recipe to make it work is just not worth the effort. I would recommend you use Serious Eats and Devil Food’s Kitchen recipes.
Devil’s Food Kitchen has more liquid, less fat (butter), and cheese in the standard ratio.
Serious Eats takes the opposite approach to ensure the dough developed the correct amount of gluten. Less liquid, a lot more fat, but less cheese to weigh the dough down.
These different approaches will produce puffs with slightly different textures and flavors. But trying both you’ll see how you can achieve a puff by counterbalancing the liquid against the fats. Then you can decide which one you like better.
I would encourage you to buy and use a scale if you plan to bake regularly. A scale is accurate and understanding your Baker’s percentages allows you to analyze the formula, decide if and what needs revision before baking; allows you to track changes; allows for scale. Baking by weight is also the most reproducible method.
If you are going to bake by volume, you need to understand that different recipe developers use different standards for 1 cup of flour. So you need to know what their standard is for 1 cup to metric conversion and how they measure flour by volume to achieve that standard.
Also, the UK and US weights and measures are different. Panama uses the same system as the US. When using a recipe from the UK, you have to convert it into Imperial measurements. For example, US fluid 1 cup measure is 8 oz = 236 mL. The UK technically is 1 cup fluid = 8.45 oz = 240mL. But the international 250mL = 1 cup is commonly used.
