In a large pot, cover the potatoes in water and bring to a boil. Then reduce heat to low, cover and simmer for approximately 10 minutes (or until the potatoes are tender).
Drain the potatoes and allow them to cool completely.
In a small bowl, mix together the mustard, mayonnaise, Tabasco hot sauce, and cumin.
In a large bowl, combine the potatoes, jalapeños, eggs, onion, and celery. Then pour the mayonnaise/mustard on top, and toss/stir the potato mix to coat completely.
For best flavor, refrigerate for at least 2 hours prior to serving.
