Notes
This recipe makes a large bowl of corn dip. If you aren't feeding a crowd, halve the recipe. Feel free to make this extra spicy with more jalapeno or more mild with less/no jalapeno. You'll find diced tomatoes with green chiles in most grocery stores in the US under the brand name Ro*Tel. We use the original version, but there are mild and hot versions available as well.
