Flavor Impact
Both cake flour and pastry flour have a mild flavor, so substituting one for the other will not significantly alter the flavor profile of your baked goods. However, because pastry flour is slightly less processed than cake flour, it might lend a very subtle nutty or wheat-like undertone that can add a touch of complexity to the flavor. This change is quite minor and may not be noticeable in recipes with strong flavor components like chocolate or spices.
Texture Changes
Pastry flour is slightly higher in protein content (around 8-9%) compared to cake flour, which has a protein content of about 7-8%. This means that using pastry flour instead of cake flour might result in a slightly denser texture with a bit more chew due to the increased gluten formation. The crumb structure will still be tender, but it might not be as fine as what you would achieve with cake flour. The mouthfeel will remain soft, though potentially not as light and airy, and the moisture retention should be similar, keeping the baked goods tender without drying out too quickly.
Structural Effects
This substitution will slightly affect the structural integrity of the baked goods. Pastry flour provides a bit more support for rise and binding due to its higher protein content, which can be beneficial for certain recipes that require a little more lift and shape retention. However, for recipes that depend on the delicate, fine crumb of cake flour, such as angel food cakes or very soft sponge cakes, this substitution might result in a less ideal structure, potentially leading to a slightly more compact and less airy final product.
