The thing about life's lessons is that they are often obvious...after one has made
the sordid mistake! Here's one such from my baking experience.
Sunday evening, already tired from a day on the computer, felt I really should bake
something for later that evening. Decided to go with a great favourite: souffle lemon cake,
with cream cheese and condensed milk but a mere tablespoon or two of flour. Thus light and
tasty. But the cream cheese was in the refrigerator and I just felt overwhelmed at the thought
of heating it on the stove to make it just right for whipping. Decided to ask Copilot how this
might be done in the microwave. Below:
The answer surprised me. I had been denaturing the cream cheese with the stove method.
So I followed instructions with three 15 second bursts. Then transferred the product to a bowl
for whipping... only to end up with cream cheese bubbles on the wall. Big mistake. I eventually
had to run the remaining cheese quite a few times in the microwave to a get a finger tested
soft product. *
Only, guess what. The cake I ended up making was utterly delicious; in effect, perfect. I had made
this beast many times, and it had never looked like this.
So there is a lesson here: Copilot found the understanding I was missing, but the engineering
problem was mine. It is a language model, and no one making that very same cake served as a
source for it's advice. I need to get smarter about THAT...
* In point of fact, I'm lying on the specifics. The remaining cream cheese was in clumps on the
bottom and sides of the largish bowl I was using...notwithstanding the clumps on the wall and
the coffee maker. I still had to add the condensed milk, five egg yolks, the juice of a large lemon
and vanilla to get a homogenous mix, so the bowl had to be large. I judged the clumps had given
me separate specimens, so I just ran the lot at high force for 15 seconds, as I would to melt
butter I wanted to put on toast( 8 seconds). One is allowed two tablespoons flour for a final
adjustment. It all worked out!! I then whipped up the egg whites in a separate bowl and poured
the two together. That was it for this recipe...

Last Sunday
I am baking a cake, and need to whip a 250 gram block of cream cheese from the refrigerator. How long should I put it in the microwave first, and at what setting?
Cold cream cheese is notoriously stubborn, so softening it just enough—without melting it—is the sweet spot for whipping it smoothly into a cake batter.
Softening a 250 g block of cream cheese in the microwave
These timings work for a standard 1000‑watt microwave:
Method
Power: 30% (low power)
Time: 15 seconds at a time
Process:
Heat 15 seconds, then press the block gently with your fingers.
Flip it over, heat another 10–15 seconds.
Stop as soon as it yields easily to pressure but still holds its shape.
Total expected time
Usually 25–35 seconds total, broken into short bursts.
Why short bursts matter
Cream cheese melts from the edges first, and melted spots ruin the texture when whipping.
Low power keeps it softening evenly rather than turning oily.
Quick test for “ready to whip”
Press the center: it should feel pliable, like room‑temperature butter.
If it’s warm or glossy, it’s gone too far.
If you want, I can walk you through getting it perfectly smooth for your cake batter.

Today
Microwave; does it take longer to melt two pats of butter than one. I'll behaving toast and the butter if from the fridge...
Short answer: yes — two cold pats take longer than one — but not twice as long.
Here’s the physics in a kitchen‑friendly way:
๐ง Why two pats melt slower
A microwave heats by exciting water molecules. Butter has very little water, so it warms unevenly.
More mass = more energy needed. Two fridge‑cold pats contain roughly double the cold mass, so they need more total energy to reach melting point.
But microwaves don’t heat linearly. Hot spots form, edges melt first, and the butter shape matters more than the exact weight.
⏱ What this means in practice
If one pat melts in, say, 8–10 seconds, then:
Two pats might take 12–15 seconds, not 16–20.
The difference is noticeable but small.
๐ง Practical trick for perfect toast buttering
Cold butter on hot toast is a classic frustration. A few reliable options:
Option A — Microwave gently
Put the pats side by side, not stacked.
Start with 5 seconds, check, then add 2–3 second bursts.
Stop as soon as the edges slump; residual heat finishes the job.
Option B — The “toast tent”
Put the cold pats on the toast, then cover loosely with another slice or a bowl.
The trapped steam softens the butter in 20–30 seconds without melting it into a puddle.
Option C — Smash technique
Use the back of a spoon to press the cold pat into the toast.
Works surprisingly well when the toast is fresh and hot.
If you want, I can help you dial in the exact timing for your microwave wattage and butter size.
So the total energy delivered to the oven is always the same...
Not quite. The microwave’s power output stays the same, but the total energy absorbed by the butter is not fixed — it depends on how long you run it and how much material is in there.
A microwave is basically a constant‑power device. If yours is rated at 1000 W, it’s dumping roughly 1000 joules per second into the oven cavity no matter what’s inside. What changes is:
๐ง How much of that energy the butter actually absorbs
One pat absorbs less energy before it melts.
Two pats have twice the mass, so they need roughly twice the energy to reach the same softness.
The microwave keeps delivering the same power, but you run it longer to get the extra energy into the butter.
So the oven doesn’t “decide” to deliver more energy — you deliver more energy by running it longer because the larger mass needs it.
๐ A simple way to picture it
Think of the microwave as a faucet:
The flow rate (power) is constant.
A small cup (one pat) fills quickly.
A bigger cup (two pats) takes longer.
The faucet didn’t change — the container did.
๐ For your toast situation
If you want fridge‑cold butter to soften fast without melting into a puddle:
Spread the pats out so they heat evenly.
Use short bursts (3–5 seconds).
Stop as soon as the edges slump.
If you want, I can help you estimate the timing based on your microwave’s wattage and the size of your butter pats.
If one pat gets a ray, then the other doesn't?
Ah, I see what you’re getting at — the “ray‑sharing” intuition. Microwaves feel like little beams that might hit one pat but miss the other. But that’s not how the field inside the oven works.
๐ Microwaves don’t fire single rays at single objects
Inside the oven, the magnetron fills the cavity with an electromagnetic field pattern. It’s more like a standing wave soup than a sniper beam.
So:
There aren’t individual “rays” that one pat could hog.
Both pats sit in the same fluctuating field.
Each pat absorbs energy proportional to its mass, shape, and position.
๐ง What can happen
Even though both pats are exposed to the same field, they may heat differently because:
The field has hot spots and cold spots.
Butter has uneven water content.
One pat might sit in a slightly hotter region.
The shape and orientation change how much energy each absorbs.
So yes, one pat can melt faster — but not because it “got the ray” and the other didn’t. It’s because the field isn’t uniform.
๐ฌ A simple analogy
Imagine two people standing in a room with uneven heating from the sun through a window.
They’re both in the same room, but one might be in a warm patch and the other in a cool patch.
The sun isn’t choosing one — the geometry is.
๐ For your toast
If you want both pats to soften evenly:
Place them side by side, not stacked.
Put them near the center of the plate.
Use short bursts so you don’t overshoot.
If you want, we can even talk about why rotating plates exist and why microwaves still have cold spots despite the turntable.
