'Instant' Latte
Instant in as much as it uses freeze dried coffee granules. Not actually any quicker than using an espresso machine and milk steamer but a good substitute if don't have one. Not the most complex process but as the only other people I know who do this are related to me I thought I'd share it.
Heat a Mug of Milk
I zap it in a microwave for 90 seconds. If you prefer you can heat it in a sauce pan on the stove. I've been told in the past that I shouldn't microwave milk as it produces nurotoxins but as I'd been doing it for years with no ill effects and have kept doing so and am still healthy I figure it's either not true, very weak or I'm immune to it.
Add Coffee Granules
place coffee granules in milk (they won't sink) if you want to add sugar do it now sprinkle it over the coffee granules. Then stir vigorously
Let It Stand
just let it sit until the movement has almost stopped (30 to 60 seconds)
Crush & Stir
not all the granules will have dissolved especially if you wanted it strong and have used 2 tea spoons of granules. draw any clumps to the edge of the mug and crush them with the back of the spoon. stir it again and it's ready to drink.
