Shrimp Ceviche and Blue Crab Dip Tostada

Pro tips

• Use the freshest raw shrimp available and marinate in fresh lime or lemon juice for proper curing; acidic juice denatures the proteins and firms the texture.
• Assemble the tostada no more than 2–3 minutes before serving to prevent the crispy shell from absorbing moisture from the ceviche.
• Layer the crab dip first as a protective barrier between the shell and ceviche to extend crispness.
• Chill both the ceviche and crab dip before assembly for a refreshing beachside bite that won't wilt quickly.

Substitutions

• Blue crab dip → lump crab salad or imitation crab mix (adjust seasoning to taste)
• Shrimp ceviche → diced white fish like halibut or mahi-mahi (cures the same way)
• Tostada shell → crispy tortilla chips or wonton crisps (reduce portion size accordingly)
• Avocado slice → sliced jalapeño or cilantro leaf (for crunch or herbaceous lift)

Storage & make-ahead

Store ceviche and crab dip separately in airtight containers for up to 3 days in the refrigerator; assemble fresh tostadas to order to maintain crispness.

Can I make this ahead of time?

Prepare the ceviche and crab dip separately up to 4 hours in advance. Assemble on the tostada shell just before serving to keep it crispy.

What's the best way to prevent a soggy tostada?

Assemble immediately before eating, or apply a thin layer of the crab dip as a barrier between the shell and ceviche to seal out moisture.

Can I substitute the blue crab dip?

Yes—use lump crab salad, imitation crab mix, or even a creamy avocado spread if fresh crab isn't available.

Is the shrimp raw in ceviche?

Yes, the shrimp is cured in citrus juice (lime or lemon) which denatures the proteins, giving it a cooked texture without heat.

How do I know when the ceviche is ready?

The shrimp should turn opaque and firm, typically after 15–30 minutes in citrus juice depending on shrimp size and juice acidity.
