Chemical Cooking Show Eliza Cummings, Ca'la Connors, and Brooke Porter What's on the Menu today? Ceviche What's ceviche you might ask? Well... Ceviche is a seafood dish, commonly found in South and Latin America. The dish is typically made from
fresh raw fish marinated in citrus juices
such as lemon or lime and
spiced with chilli peppers. Ceviche originated in Peru and Ecuador Ceviche can served with crispy tortilla's, with side dishes, or all on it's own It can be made with Red snapper, sea bass,
marlin, pompano, sole, shark, tilapia, tuna,
squid, scallops, octopus, shrimp, or crab or
a combination of several Safety and Precautions Always remember to wash
your hands when handling
food and cooking utensils Since you're not using
heat to denature your
chosen protein, be sure
to marinate the protein
long enough to cook all the
way through Always buy fresh ingredients,
the seafood in particular, to
avoid expired and potentially
dangerous to eat food Please use caution when using
sharp cutting utensils and avoid injuring yourself Needed Ingredients
for Shrimp Ceviche: One pound
of shrimp 2 tablespoons
of salt 3/4 cup of
lime juice 3/4 cup of
lemon juice One cup of chopped
red onion One serrano chile pepper One cup of
cilantro one avacado One cucumber Directions: 1. You can either marinate
and cook the shrimp in your lemon and
lime juice for 3-4 hrs. in a refridgerator
for those who are more timid and nervous
about eating unconventionally cooked shrimp
you can: In a large pot, bring to a boil 4 quarts of water, salted with 2 Tbsp salt. Add the shrimp and cook for 1 minute to 2 minutes max, depending on size of shrimp. 2. Drain the shrimp. Cut each piece of shrimp in half, or into inch-long pieces. Place shrimp in a glass or ceramic bowl. Mix in the lime and lemon juice. Cover and refrigerate for a half hour. 3. Mix in the chopped red onion and serrano chile. Refrigerate an additional half hour. 4. Right before serving, add the cilantro, cucumber, and avocado Chemical Concepts: Denaturing- modify as a native protein especially by heat, acid, or UV radiation so that all the original properties are removed or diminished Coagulation- A separation or precipitation from a dispersed state of suspensoid particles resulting from their growth; may result from prolonged heating, addition of an electrolyte, or from a condensation reaction between solute and solvent Endothermic reaction: a chemical reaction accompanied by the absorption of heat Boiling: the application of heat to change something from a liquid to a gas pH scale- a scale of 14 of which 1 is considered to be the most acidic and 14 is the most basic, seven is neutral. Conduction- the transfer of heat between two items that are in direct contact with each other Convection- the transfer of heat through a liquid or gas Heat-a form of energy that is transferred by a difference in temperature
