In the 1940's spherification was discovered by mistake by a food scientist and used in molecular gastronomy since. It is simply the method of turning liquid into the shape of a sphere. In this class we use this process to create an edible juice bubble. The learners will be introduced the science behind spherification while participating in a hands-on exploration. Once the students master the basic technique they will learn how to make various sizes and the application of each in food science....
Students will improve their knowledge in molecular gastronomy: - what is a colloid? - what is sodium alginate? - why is sodium alginate required for this reaction to work? Students will also use skills of measurement, operational steps, and critical thinking
CALCIUM LATATE POWDER (you will need 9 grams or 2.5 tsp in total) you can substitute this with calcium chloride or calcium lactate glutanate SODIUM ALGINATE powder (you will need 1 gram or 1/2 tsp) WATER (filtered tastes best, but tap is fine) BLENDER (can use a whisk if you do not have a blender) 1 MEDIUM BOWL (should be able to fit 2 cups (500 mL) of liquid) 2 SPOONS 2 SMALL BOWLS (should be able to fit 1 cup (250 mL) of liquid in each) tablespoon and teaspoon MEASURING SPOONS MEASURING CUP SYRINGE (the size (diameter) of the syringe tip is the size the boba will be) - I use a 20 cc syringe (no needle) - You could also use a straw, baster, squeeze bottle, or a spoon A FLAVORING for the boba - no pineapple juice, lemonade, coffee, or orange juice - I find that shaved ice syrups, soda, mango juice (less than 2% Calcium), and capri sun all work well (these are not the only flavorings that work though - you can feel free to message me if you have any questions regarding the flavoring you would like to use.) BAKING SODA SIEVE OR SMALL STRAINER
Learners will not need to use any apps or websites beyond the standard Outschool tools.
1 hour per week in class, and maybe some time outside of class.
Supervision may be required with an immersion blender.
