Rest calorie burn rate

Self-tutoring about health: the tutor pursues the idea of how many calories a person might burn per minute, at rest.

The rest calorie burn rate is approximately 1.2 per minute for a person of mass 70kg.

Back in my post from August 16, 2017, I reported 80 to 100 Watts as the power needed to stay alive. Taking 90W as the average, it leads to 1.3cal/minute.

When discussing fitness, the calories mentioned are nutritionist calories. In physics, 1 nutritionist’s calorie=1kcal.

Sticky dough: possible cause and solution, part II

Self-tutoring about baking: the tutor follows up on the idea of sticky dough.

Back in my post on July 21, I mention dough being to sticky to work: it stuck to my hands so I couldn’t knead it. The same happened again yesterday.

My wife agrees with other sources that the solution is to add more flour, which solved the problem easily. She further observed that the higher temperature in the house during summer might cause the dough to be more active, hence stickier.

The recipe I was using calls for three cups flour – see it here. Now, when making it during hotter conditions (the temp in the house last time was 26°C), I’d be ready with 3 1/2 cups flour, or even more. (Back before I had the problem with sticky dough, the house temperature was 23°C).

With the extra flour added, the scones turned out fine:)

Dough too sticky – what to do?

Self-tutoring about baking: the tutor mentions a problem he sometimes encounters, with possible workarounds.

This morning, making scones, the dough was too sticky to work with – it wouldn’t let go my hands. I wondered what to do, and added about a half cup of milk. It made the dough workable, though not like normal. However, I did get it cut and into the oven. The scones were a little fluffier than usual, but fine.

Everyone else says I should have added more flour instead of milk. I’m not 100% convinced, but maybe I’ll try that next time. The “sticky dough” happens to me about one in ten times – I don’t know why.

Can you substitute lard for butter?

Cooking self-tutoring: the tutor experiments substituting lard for butter.

A scones recipe calls for butter…what to do if you haven’t any? Normally I use margarine instead.

Today, hoping for scones that would be a little more crumbly, I used lard instead of margarine. It worked.


Here’s the scones recipe in which I made the substitution:

Do you use your agenda?

Self-tutoring in psychology: the tutor reflects about organizational habits.

My wife and I use a common agenda to coordinate schedules, including the kids’ activities. It’s used not only to remind us, but just as much to prevent double-bookings.

When my thirteen-year-old brought his school supplies home last week, he left them on the dining-room table. In solitude, I examined his 2017-2018 agenda.

His name is written on the front, by my wife. Inside he makes one entry: “Lecture”, printed for Tuesday, September 12.

My son’s year was successful…he obviously didn’t need to use his agenda beyond that single entry. All those empty pages, those empty boxes that represent days he spent at school, offer mysteries of what actually happened.

I don’t use organizers nearly to the extent of some people, yet in some contexts they can suddenly be very important. Hence, I will be happy to provide him with an agenda for the coming year, whether he needs it or not. I need to provide it to him, because it will represent another year with so many days which may, individually, need organization.

As for his agenda from this year, empty but for one word, and dated 2017-2018…I’ll keep it:)

Crunchy peanut butter vs smooth: which is more popular, and by how much?

Self-tutoring about peanut butter preference: the tutor inquires about the popularity of crunchy vs smooth.

We eat a lot of peanut butter, but have gone years without buying crunchy. I’d say 95% of the peanut butter we’ve ever bought has been smooth.

Yet, I notice crunchy peanut butter every time, and want to get it. I’ve always liked it, but of course, I like both. The question that finally crystallized in my mind: who does buy crunchy peanut butter, if we so rarely do?

It turns out about 60% of people prefer smooth peanut butter. I thought the difference would be much higher.

Recently we’ve been buying some chunky, some smooth:)

What is clarified butter, and what is ghee?

Self-tutoring about cooking: the tutor arrives at the definitions of clarified butter and ghee.

Clarified butter and ghee are not the same but can be explained as follows:

  1. Clarified butter is begun by heating butter at low heat so that it melts.
  2. As the butter melts, solids will sink to the bottom and a foam will form on top.
  3. The clarified butter is just the liquid without the foam or solids.
  4. If the butter is heated for longer, the liquid will deepen in color and the foam will solidify and sink. Then, the liquid is ghee.

How to keep eggshell out of your baked goods

Self-tutoring about baking: the tutor shares a simple trick.

When you bake something, you definitely don’t want eggshell in it. Of course, it usually wouldn’t happen. However, the odd time, an egg might crack irregularly, so that a piece of shell separates from the rest and lands in the bowl with the egg.

It’s easy to retrieve the shell fragment if you can see it, which is why I try to remember to use a dark-colored bowl, and put the eggs in first. Then, if a shell fragment lands in the bowl, it’s easy to see and remove.

A rub for chicken legs

Self-tutoring about cooking: the tutor shares a find.

I searched up a rub to elevate some chicken legs on the barbecue and found this one from Brenda McGrath at, a site I often visit for recipes.

I rubbed the chicken legs in it, then indirect-grilled them on the barbecue at medium-high heat for about 80 minutes.

One of my kids commented that the chicken legs tasted “like barbecue chips.” Everyone loved the rub. Thanks, Brenda!

Why flour a cake pan?

Self-tutoring about baking: the tutor wonders why flour a cake pan.

Apparently there are two reasons to flour a cake pan:

  1. Help support the batter as it rises against the pan.
  2. We assume that the pan has been buttered before floured. Then the flour reduces the melting of the butter into the dough.

An idea I read is that, for a chocolate cake, you can dust the pan with cocoa instead of flour to serve the same purpose. Neat, eh?
