The best trick, and it is genuinely fast: grate it.

Take the cold block and run it over the coarse side of a box grater. Two things happen at once — the mechanical work warms it slightly, and the surface area increases enormously so the room temperature does the rest. A pile of grated butter is at spreadable softness within a couple of minutes and is easy to incorporate even before that.

The runners-up:

Cut it into small cubes and spread them out. Slower than grating, no equipment.

Pound it between parchment with a rolling pin. A block flattened to a few millimetres softens quickly and warms evenly.

A warm bowl. Fill a bowl with hot water, empty it, dry it, and invert it over the butter. Gentle ambient heat, no direct contact.

The microwave, correctly. Five seconds, press it, five more. The problem is not the microwave, it is that the heating continues after it stops and that butter heats very unevenly.

The other lever is starting temperature and time.

Take the egg out of the fridge first, or run it under warm water for a minute. A room temperature egg needs noticeably less energy from the water, and it is also less likely to crack.

Give it longer than you think. The flask method is gentle — the water is below boiling and there is no agitation — so it takes considerably longer than a rolling boil. Twenty to thirty minutes rather than ten, and there is no real penalty for leaving it longer since the temperature is dropping rather than rising.

That last point is the appeal of the method: it is genuinely hard to overcook. The temperature falls slowly, so an egg left an extra fifteen minutes is fine, where the same in a pan gives you a grey ring.

For anything you buy that you are uncertain about: the shop will replace it without argument.

Retailers deal with this constantly and would far rather exchange a carton than have a customer take a chance. If the squeeze test is ambiguous and you are not comfortable, it is a two-minute conversation and no reasonable shop makes it difficult.

One practical note on the peel: an unwaxed fruit makes a noticeable difference, and washing waxed fruit in warm water first helps if unwaxed is not available.

The wax coating sits exactly where the oil is, and it both blocks extraction and contributes nothing good. Whichever fruit you use, a scrub in warm water before peeling costs a minute.
