Step 1

Bring 1 quart (1L) of salted water to a boil. Add the shrimp and let the water return to a simmer and poach for an additional minute or two. Scoop the shrimp out and place onto a rimmed baking sheet and chill 30 minutes. The shrimp can be made a day in advance and chilled until ready to serve.

Step 2

For the sauce, stir together the ketchup, lime juice, the Mexican hot sauce, olive oil and cilantro in a large bowl. This step can be completed a day in advance, stored in the refrigerator in an airtight container.

Step 3

In a small strainer, rinse the onion under cold water, then shake off the excess liquid, and add to the sauce. Peel, dice and add the jicama; dice and add the cucumber. Stir in the chilled shrimp and the avocado right before serving.

Step 4

Garnish with lime and serve with tostadas, chips, or saltine crackers.
