The best spinach dip w/ chipotle lime

2 10-ounce packages frozen spinach, thawed and drained
8 ounces cream cheese (about 1 cup), softened
1/2 cup mayonnaise
1/2 cup sour cream (see note)
1/2 cup sliced scallions
1/3 cup chopped cilantro
1 tablespoon chopped chipotle in adobo sauce, or more to taste
1 tablespoon freshly squeezed lime juice, or to taste
3/4 teaspoon kosher salt, or to taste
Freshly ground black pepper
Tortilla chips, for dipping.

1. Bundle spinach in a clean dishtowel and squeeze very tightly to remove all excess moisture.

2. In a food processor, blend together all ingredients except spinach until very smooth, about 90 seconds. Pulse in spinach until just combined. Taste and adjust seasoning, if necessary. Serve with tortilla chips.

Yield: About 3 cups.

Note: You can omit the sour cream and increase mayonnaise to 1 cup.
