How can I melt cheese for dipping?

Normal cheese melts like that. It is made of proteins, fats, and water, and these separate when they are heated.

For dipping, you need processed cheese. It has additives which keep the fat, fluid and solids mixed in a smooth mass. Also, it really helps to use very slow and even heat. This is the easy option.

If you want to do it "for real", without processed cheese, you have to make a cheese fondue. It is traditionally made with Swiss cheese (I am fond of Appenzeller fondue), but you can use most types of semi-hard yellow cheese. It also contains some fluid, traditionaly white wine, and is emulsified with simple starch. It is preferable to have a special pan for this, as you can serve it heated. But if you make a big portion in a pan with a high thermal capacity, and make it immediately before serving, you can do without the special gear.

Try heating a couple table spoons of butter with some flour in a pot for a couple of minutes stirring with a wooden spoon then add enough hot milk to make the mixture smooth. Melting the grated cheese in flour prevents the oils from separating and the proteins from curdling.

(edit) If you want to search for a recipe, a Béchamel sauce with grated cheese added to it is called Mornay sauce

There is the good way and the cheap way.

The good way is fondue. Acid and / or alcohol are used to cut up the cheese proteins so it isn't stringy and the cheese is heated gently to not break the emulsion.

You can look up a recipe. <napoleonDynamite>There are, like, an infinity of them.</napoleonDynamite>

The cheap way is processed cheese product. This is most likely what you would have seen for casually dipping a pretzel.

This is a mixture of cheeses that are melted together with emulsifiers and gums and various other things that make them melt smoothly.

Velveeta would be the canonical brand name for this sort of thing.

Around here they like to mix salsa into it, use it as a dip, and call it 'queso' which, in my mind, is both a culinary and linguistic atrocity.

Without taking away anything from the previous answers, I want to add one more reference: Kenji Alt's article on making a perfectly smooth cheese sauce.

He describes the science in great detail, as well as providing lots of documentation of his various experiments. His final recipe comes down to a simple methodology:

• Toss the real cheese, shredded, with corn starch which will act as an emulsifier to help keep the sauce from breaking
• Add condensed milk to increase the amount of milk proteins and water
• Melt slowly

You will note that in many ways, this parallels the very classical fondue recipe that Rumtscho has referred to. It uses starch as an emulsifier and adds liquid (from the condensed milk, instead of wine). The major difference is substantially increasing the protein level (via the condensed milk).

You can prevent prevent cheese from separating as it heats by adding sodium citrate to the recipe. Sodium citrate is the same ingredient used as the binder in processed cheese and wine-based cheese recipes.

I bought a bag from Amazon that will last me a lifetime: http://www.amazon.com/Sodium-Citrate-Non-GMO-Molecular-Gastronomy/dp/B00BLPNM62/ref=sr_1_2?ie=UTF8&qid=1418940460&sr=8-2&keywords=sodium+citrate

Here is a simple and excellent cheese sauce recipe that lets you make creamy sauce using high-quality cheeses: http://www.chefsteps.com/activities/cheddar-cheese-sauce

No one knows how far back this kitchen wisdom goes, but in 1912 two Swiss food scientists were working on the problem of sterilizing cheese so that it could be stored, unrefrigerated, in hot climates. Up until this point, the results had been greasy failures; but these scientists discovered that adding the salt of citric acid (sodium citrate) to the cheese could prevent oiling-off. They had invented processed cheese.

An EXCERPT from the Huffington Post article "How To Make The Creamiest Nacho Cheese." Entire article at: http://www.huffingtonpost.com/2012/01/12/how-to-make-nacho-cheese_n_1202697.html

(I leave out the salt since cheese is salty enough for me.)

2 tablespoons butter, 2 tablespoons flour, 1 cup milk (warmed), 8 slices cheddar cheese, 1/2 teaspoons salt, Jalapeno peppers (optional)

1. Melt the butter over medium-low heat in a saucepan.

2. Whisk in the flour one tablespoon at a time to avoid clumping.

3. Add the milk after the flour has settled. Mix until the sauce has an even consistency.

4. Add the cheese and salt. After the cheese has melted, turn the burner to low, and allow the sauce to simmer for 10 to 15 minutes.

Melt (nuke) shredded cheese in milk until it's soft, near melted. Add sufficient cream cheese to soak up the excess milk and form a dip-like substance when mixed. Works with most cheeses. For instance, you'll get a smooth, yellow cheddar dip. The effect of cream cheese on flavor is pretty minimal. Its effect on texture and oiliness is wonderful.

I think you can just melt cheese. You need:

• a bowl.
• cheese. (shredded is best.)
• a microwave. (duh.)
• a fork.

Put the shredded cheese in the bowl. It depends on the time you put the microwave on.. First do a minute, if it's not melted, do 2 minutes. If it's still not, then set it on 3 minutes. Take the cheese out of the microwave and grab a fork. Stir it. There may be some greasy stuff in there. Dump it out. So there ya go! You can add milk, I think it makes it less thick.

For all the home cooks bechamel is not the same as melted cheese. The only way to keep pure melted cheese from separating is with sodium citrate, but it will set up if you let it cool down again.

I can confirm that cornstarch (cornflour if you're in the UK) and evaporated milk works a treat.

By the way, condensed milk and evaporated milk are not the same thing. Condensed milk is really sweet and used for confectionary. It would make a very sweet caramelly cheese sauce. Which sounds gross to me.
