I have been testing and testing and I finally have for you today the BEST Queso Blanco that tastes just like what you get in Mexican restaurants! AND it's only 4 ingredients and ready in about 20 minutes!
Place all ingredients (evaporated milk, diced jalapeño, freshly shredded white American cheese and freshly shredded pepper jack cheese) in a medium sized pot over medium low heat.
Whisk to combine ingredients and then increase heat to a medium, whisking occasionally to prevent burning.
Once cheese has completely melted and sauce has thickened (about 5 minutes), taste for seasoning, and remove from heat.
Transfer to a serving dish and serve with tortilla chips!
Notes
*Do not use pre-shredded cheese, as it has anti-clumping agents that will also prevent it from melting. We want a smooth consistency, so shred it yourself. Alternatively, you can buy cheese SLICES from the deli and those will melt just as well. **You also do not want to use American "pasteurized prepared cheese product" singles here - that is not real cheese and will not give you the same end result. ***Pro Tip for tasting for salt: Make sure you taste the queso with a tortilla chip because those are salted and this will prevent you from oversalting.
