I do not need to brag, however…okay, I do need to brag. I make one of the best angel meals cake on the earth. It puffs up like a cloud within the oven, towering up out of the pan, and each slice is so fluffy, it makes whipped cream look dense.
The key ingredient? Cake flour. Milled from comfortable wheat, it is much more delicate than pastry flour, with a protein content material of ideally not more than 8%. Although that is solely two to 5 factors decrease than all-purpose, it is a vital distinction in terms of cake batter, which comprises considerably extra water than cookie dough, a state that facilitates gluten formation.
For over a century, American cake flour has additionally been bleached, however lately, a number of producers have launched unbleached options (whereas DIY fans choose to make theirs at dwelling). I will eternally and all the time champion any firm that widens the marketplace for high-quality flour, and any baker who prefers do-it-yourself. I unconditionally help everybody’s proper to resolve what meals belong of their pantry.
The Chemistry of Baking
That does not imply I am prepared to throw bleached cake flour below the bus just because it is a chemically processed meals. From sucrose to sodium chloride, baking is determined by chemical substances at each flip. I imply, what’s a recipe if not a formulation written in a language anybody can perceive? Nobody will get enthusiastic about C12H22O11,Δ = 2H20 C24H36O18, however we will all agree that sugar + warmth = caramel, and that is one thing grand…notably with a beneficiant dose of NaCl. I imply, sodium chloride, er, uh, salt.
See what I imply?
In terms of understanding the chemistry of baking, it is essential we not draw back from, nicely, chemistry! There is not any cause to reject an ingredient just because its identify may be expressed in scientific phrases. I will readily admit that bleached does not sound scrumptious, nevertheless it’s a exceptional and broadly misunderstood course of that deserves greater than a abstract judgment.
How Flour Is Bleached
To know why cake flour is handled with Cl2, higher often called chlorine, we have now to rise above Lovejoy’s Legislation and hyperbole—who desires to drink bleach, yuck! Such rhetorical units willfully ignore the aim of chemical remedies, and grossly exaggerate the scope of chlorine’s use.
For starters, producers aren’t pouring buckets of chlorine into cake flour—they’re treating it via low-level publicity to chlorine fuel. We’re speaking about concentrations starting from 0.008% to 0.3% relative to the load of the flour. However under no circumstances, form, or type does that a lot chlorine wind up in your meals.
The entire level of including chlorine is to impress a response, in order that when the fuel mingles with cake flour, each are reworked. The flour undergoes a collection of chemical interactions that disrupt glycosidic bonds, depolymerize starches, and oxidize lipids, amino acids, and carotene. That is quite a lot of scientific jargon, however what it means is that the flour is not merely whitened; it is conditioned in a manner that impacts absorbency, taste, and pH.
In the meantime, the chlorine is modified, too. Coming into contact with the flour’s personal water content material triggers hydrolyzation, a response that leaves behind chlorite (naturally occurring in unbleached flour), hypochlorous acid (one thing our personal immune cells produce to battle an infection), and chloride (a vital electrolyte).
There’s some actual cognitive dissonance happening once we draw back from bleached cake flour over “scary” chemical substances like chloride, then pay further for chloride in bottled water just because manufacturers are sensible sufficient to invoice it as a mineral or electrolyte as an alternative. It is only one small instance of why we must always consider elements for what they’re, not how they’re framed.
Though, come to think about it, American millers would in all probability have a better go of it with a rebranding effort—Sensible Flour: Electrolyte-Enhanced for Improved Efficiency in Cake! In comparison with the doubtful claims of sure bottled drinks, no less than that may be true. Chlorinated cake flour improves the amount, construction, crumb, and dome symmetry of high-sugar cake formulation in scientifically measurable methods, as demonstrated in examine after examine after examine.
What research have not proven is that the by-products of chlorination current any danger to customers. On the conclusion of a generational examine designed to watch the long-term affect of a weight loss plan primarily based on chlorinated cake flour, a British analysis workforce concluded that “no carcinogenic, teratogenic, or different poisonous results attributable to chlorination had been noticed.” (You’ll be able to learn the summary right here, or pony as much as get behind the paywall to peruse the paper in full.)
The absence of proof is, after all, not proof of absence. I am not saying we should not proceed investigating the affect of chlorination in flour processing; solely that our resolution needs to be knowledgeable, not reactionary. I’ve spent months analyzing the literature, following the research, talking with meals chemists, and studying up on finest practices from the World Well being Group. WHO has no gripe with chlorinated flour in any respect. On the finish of the day, I am unable to provide you with a single cause to desert chlorinated cake flour that would ever outweigh its confirmed advantages.
Specifically: this fluffy, tender, four-inch magnificence.
How Bleached Flour Works
Chlorine remedy alters the conventional charge of starch gelatinization in flour, slowing it in a manner that improves fuel retention. This permits the batter extra time to rise, leading to super-lofty, fine-grained truffles. Doubling down on that impact, chlorination additionally raises the temperature of protein denaturation, likewise shopping for the cake extra time to rise.
What’s extra, chlorination lowers the pH of cake flour from a mean of 5.9 to about 4.8. The shift towards acidity inhibits browning, a significant no-no for crusty breads and golden cookies, however a stunning contact in terms of the snowy crumb of an angel meals cake. Inhibiting the Maillard response can be useful in highlighting delicate flavors, like almond or vanilla, that may be overwhelmed by the darker toffee notes of browning.
Why would I ever surrender a cake like that? Particularly contemplating how unbleached options fall flat. Actually.
That cake was constituted of the identical batch of egg whites and the identical method, similar oven, similar cake pan, similar batter temperature, similar baking time, similar cooling methodology, similar cooling time. The one distinction is that I opted for unbleached cake flour, which soaked up an excessive amount of moisture and set too shortly to let the cake rise. And, should you’re questioning how folks made angel meals cake with out bleached cake flour within the days of yore, the reply is: They did not. The historical past of angel meals cake is immediately tied to the invention of bleached cake flour within the nineteenth century, however that is an entire ‘nother story.
Not solely is unbleached cake flour out of the query, DIY options are, too. Baking consultants are weirdly fast to vow that making do-it-yourself cake flour is as easy as reducing all-purpose flour with cornstarch, nevertheless it’s not that straightforward. Cornstarch could dilute the general protein content material of the flour, nevertheless it jacks up the starch in a completely completely different manner. The result’s a extremely absorbent dry combine that soaks up manner an excessive amount of moisture, for a cake that bakes up heavy and dense.
No less than in terms of a recipe as delicate as angel meals cake, DIY cake flour simply cannot examine (nor can it match the low pH of chlorinated cake flour). Granted, it is nonetheless a more sensible choice than unbleached cake flour, nevertheless it makes angel meals moist and spongy and difficult. It might work in a pinch, however the higher possibility could be to make one thing else.
Due to its efficiency, and the conclusions I’ve drawn from my very own analysis, bleached cake flour will all the time have a spot in my pantry, notably contemplating the very restricted scope of its use: a novel subset of recipes which are supposed to be loved sparsely. You could really feel in a different way, and that is okay! You could need to do your personal analysis, and it’s best to! The necessary factor is to enter your resolution nicely knowledgeable, and hopefully I’ve offered sufficient data to get you headed in the proper course.
