In a medium-size, heavy-bottom saucepan, melt the butter over medium-high heat.
Add the flour blend all at once, and whisk to combine well.
Allow to cook, whisking occasionally, until the the mixture is well-combined and has started to become fragrant (about 1 minute).
Add the milk in a slow but steady stream, whisking constantly, until well-combined. Add the salt, pepper and sugar, and whisk to combine.
Bring the mixture to a boil, whisking occasionally, and continue to cook until the mixture begins to thicken (about 6 minutes).
For thicker creamed corn, continue to cook the mixture until it has thickened further and reduced a bit.
Add the corn kernels, and whisk to combine.
Cook until the corn is heated through.
The creamed corn will thicken as it cools. For a thinner consistency, add more warm milk a few tablespoons at a time.
Serve immediately or cool completely, transfer to a well-sealed container and store in the refrigerator for up to 4 days.
Reheat over low heat before serving, adding more milk by the tablespoon as necessary to reach your desired consistency.
Notes
Flour blend infoAny smooth, no grit properly balanced gluten free flour blend with superfine rice flour as a base and no gums will work here. You can use our gum-free gluten free flour blend, made from superfine rice flour, potato starch and tapioca starch, Nicole's Best multipurpose (which is made without gums), or Vitacost's Multi-Blend Gluten Free Flour without gum will all work well.
