Finely shred the cabbage and grate the carrot. Dice the bell pepper, onion, and pickles into small pieces so every bite has a good balance of crunchy vegetables and creamy dressing.

In a large mixing bowl, whisk together the mayonnaise, sweet pickle juice, white vinegar, sugar, salt, and black pepper until smooth and creamy. The pickle brine gives the dressing its signature tangy flavor.

Add the shredded cabbage, carrot, bell pepper, red onion, and chopped pickles to the bowl with the dressing. Toss gently until the vegetables are evenly coated.

Taste the coleslaw and adjust the seasoning as needed. Add a little more pickle juice for extra tang, sugar for more sweetness, or black pepper for a sharper finish.

Fold in the chopped fresh dill, if using. Keep the mixing gentle so the cabbage stays crisp rather than becoming overly soft.

Cover the bowl and refrigerate for at least 1 hour before serving. This gives the vegetables time to absorb the creamy, sweet and tangy dressing.

Give the coleslaw a final toss just before serving. Transfer it to a serving bowl and garnish with a little fresh dill or finely chopped pickle, if desired.
