Recipe for "Covid Cocklewarmer"

Try this if you are bored with being cooped up at home.
This is my peanut-butter coffee recipe, and as such, it is a caffeinated beverage that will activate your brain. If you are like me, your brain is always your best source of entertainment.

Both versions make one serving.

Store the tap water in a refrigerator at 4–6°C.

Do not serve hotter than 56°C or the mixture breaks like Hollandaise. (But it's much easier to fix: just let it cool for a bit and then swirl.)*

To go hotter than 56°C without breaking, microwave the water longer to taste and add a tablespoon of milk before shaking.

Instant coffee version:

• Add 300 mL of water to a mason jar free of scratches.
• Heat jar in a 700-W microwave at maximum power for 2 min 30 sec without lid.
• Add 1 tablespoon (15 mL) of sugar.
• Add 2 tablespoons (30 mL) of instant coffee.
• Add 2 tablespoons (30 mL) of smooth, non-separating peanut butter.
• Put on a glove or pick up a dishcloth for comfort in handling the hot jar.
• Close lid and shake the jar up-and-down vigorously for 15 sec.

Filter coffee version (preparation time, 10 min):

• Add 400 mL water to a mason jar free of scratches.
• Heat jar in a 700-W microwave at maximum power for 3 min 40 sec without lid. Aim for 75°C.
• Pour the water into a large plastic cup. Test the cup first to see if it is melted by the hot water; some are and some aren't.
• Place a filter containing 3.5 tablespoons of fine-grind coffee on the jar.
• Pour the water through the coffee.
• Remove the filter.
• Add 1 tablespoon (15  mL) of sugar to the jar.
• Add 2 tablespoons (30 mL) of smooth, non-separating peanut butter.
• Put on a glove or pick up a dishcloth for comfort in handling the hot jar.
• Close lid and shake the jar up-and-down vigorously for 15 sec.

Note 1: Do not add a hot mixture to a cold container and then shake. This will cause the container to suddenly pressurize at the first shake, with unpredictable consequences. 

This filter gives the slowest percolation and therefore the best kick of the three that I have tried. Don't bother to change the microwaving time.

*Note 2: Kraft "Extra-roasted" peanut butter <07-12-2021: and now, the regular kind> can be pushed to 60°C in this recipe without breaking, but the mouth feel is not as good. <07-25-2021: JIF is better.>

01-14-2022: Peanut-butter tea tastes like walnuts. It’s like somebody made a milk substitute out of walnuts instead of almonds. Not bad. It doesn’t curdle like peanut-butter coffee either, at least not at 72 C (162 Fahrenheit). I used double-strength green tea, but followed the rest of the above recipe.

Here is an update on my cocklewarmer setup, 2.5 years on.
