Like many people learning the culinary arts, I started by trying to cook something on a range top. What I did not realize is that cooking also involved no heat at all.
The most common would be salads. Now don't get me wrong there are some salads that are served warm or hot, but that is for another time.
You can also prepare certain types of fish using citric juices such as Lemons, Limes or Oranges. This type of cooking relies on the fruit juice acids to do the cooking. Some of the fish types that do well with this method of cooking are Cod, Tuna, Salmon, Orange Roughy, White Fish or any type of fish that gets flakey when cooked using heat. Other ingredients that do well are shrimp, calamari, pre-cooked octopus, cucumbers, thinly sliced carrots, onions, tomatoes and yes even lobster. Actually most any vegetable you might like can be an ingredient in this cooking method. You can also enjoy a good old fashion tuna salad with chopped pickles and onion mixed with mayonnaise; salmon can also be substituted for the tuna.
With the introduction and widespread use of pre-cooked meats the boundaries are opened up even further.
Sliced deli meats are great not only for subs and sandwiches but can be filled with herbed cream cheese, thinly sliced veggies, hard chunk cheeses or soft cheeses for that matter. Pre-cooked beef roasts, pork, chicken, smoked turkey, ham or chickens are also very handy to have around. Use larger pre-cooked meats chopped or cubed into salads or if you like to slice your own deli style cuts for rolls or sandwiches.
Fruits and vegetables are also easy to use without having to cook. Cut your own fruit and make your own fruit salads. You can add a little sugar or a sweet wine to the mix. You can even finely grate parmesan or pecorino or any mild hard cheese and sprinkle over the top of your fruit mix.
Veggie platters are quick and easy with your favorite dip. You can even thinly slice or julienne carrots, celery cucumbers, lettuce or cabbage and use spring roll sheets and make your own spring rolls and you can drizzle an oil vingerette over the top or on the inside.
Of course you can take full advantage of modern conveniences and for dessert make up some instant puddings or add whipped cream to your made pudding and pour it into a pre-baked pie crust and voila, cream pie.
If you would like an appetizer, set a package of flour tortillas out until they reach room temperature and soften cream cheese or cheese spread and spread a thin layer on one side of the tortilla then layer sliced meats or thinly sliced veggies and / or cheese then roll tightly and slice into ¼ inch disks and there you have a delicious and quick finger food.
Salsas can also be made without heat or you can make your own avocado quacamole, add a few chips and it's snack time.
Remember you are only limited by your imagination when it comes to cooking even cooking without heat.
