Of course. Just enter the name of the publication or blog in speech marks in the Library Recipes e.g. "Cook's Illustrated" (36,556 recipes) or "Smitten Kitchen" (1,536 recipes). And you can add a sort such as Publication date. Then add your recipe search words and filters to the selected recipes.
If you have all the selected search publications already on your Bookshelf, then you can apply the same search to My Bookshelf Recipes. That way you can bookmark recipes as you scroll through the results.
