There are extensions which try to extract the recipe out of the page and display it directly.
e.g. for chrome (I don't endorse this, just an example): https://chrome.google.com/webstore/detail/recipe-filter/ahlc...
A problem is that sometimes the bloggers will write modifications or amendments mixed into their prose, and not reference them in the actual recipe instructions (e.g. the recipe calls for 400g of flour, but somewhere in the autobiography, the author says "The recipe calls for 400g but I find 600g to produce a much better end result")
I think, ultimately, one should not google around for recipes from random bloggers, and instead only take recipes from actual cookbooks. When you find a random person's blog, you have no idea what their skill levels are, what their motivations are for writing(usually just to make $$$ via a blog). For example, I ran across a recipe which the end product had raw flour in it, and a commenter on the site said that they should put a warning for pregnant people to not do this, and the blogger came through and said that raw flour is not only not bad for pregnant women, but is actually good for pregnant women, which goes against all known advice from healthcare professionals.
