All-Purpose Flour (Best Option)
1:1 by weightAll-purpose flour contains about 10-12% protein, which is lower than bread flour but still sufficient to create the starch network needed for thickening cream sauce. The gluten development is moderate, preventing the sauce from becoming too elastic or gummy.
To ensure a smooth sauce, whisk the flour into melted butter to form a roux and cook it long enough to eliminate raw flour taste before gradually adding cream or milk. Avoid overheating to prevent clumping.
Compared to bread flour, all-purpose flour produces a slightly less robust thickening effect but yields a creamier, more traditional sauce texture that is generally preferred in cream sauces.
