Banana-Parsley Milk Shake (TGRWT #2)

Traduction: [ Google | Babelfish ]

Catégories : [ Cuisine ]

tgrwt2

Food pairing is fun, because it looks absurd at first sight. Then you think about it, and it still seems improbable. Then you taste it, and… sometimes it's good, sometimes it's not ;)

This second edition of They Go Really Well Together started by Martin at khymos.org is now hosted by Tara at Should You Eat That?. This time, the goal is to associate banana with parsley. I did it with an obvious parsley enhanced banana milk shake.

Ingredients

  • 2 ripe bananas
  • 100g vanilla ice cream
  • about 5 dL milk
  • 5 cL fresh parsley

Preparation

Banana-Parsley_Milk_Shake

Peel and slice the bananas into a blender. Add the ice cream cut into small parcels (otherwise you might clog the blender) and the milk. Mix until smooth.

In a small and fast blender, chop the parsley. Add about 2 dL of milk shake, and mix until smooth.

Comment

It's foamy and creamy like any banana milk shake, but definitely much more green! The first attempt smelled and tasted obviously of banana and vanilla, with a hint of something else you can't recognize. The parsley then bursts out in the aftertaste.

In the second attempt I put a little less parsley (the leftovers of the bouquet, actually), and whereas it looked the same and tasted fine, the aftertaste was absent. I suppose numerous experiment and a precision scale (for weighing the parsley) would be necessary to be able to reproduce the recipe.

I dug again into my hacked blosxom to find more ugliness, such as opening files for all the stories, including the ones that are not going to be displayed. This divided the time spent in blosxom::generate by 3.

Surprisingly, replacing the look-behind assertions in interpolate_fancy::__ANON__'s regexps didn't made as big a difference as in textrite::rite (1.11 ms against 0.813 ms), probably because there wasn't that many of them and weren't called that often

Profiling results are now like this:

The User+System Time is lower, but for some reason the Total Elapsed Time is about the same.

The problem in textrite::rite came from the use of look-behind assertions in Perl regexp. I've changed all of them so that look-behind is not needed anymore. The same problem occurs in interpolate_fancy::__ANON__, but I'm not going to look into it yet.

The other problem was that textrite::rite was called for all the stories, including the ones that were not displayed (which was most of them). I changed the internal structure of the main script so that the processing of the story happens after discarding the non-displayed ones.

Production de CO2

Catégories : [ Science ]

Un litre d'essence produit 2,4 kg de CO2, donc ma voiture qui a consommé en moyenne 6,8 L/100 km ces deux dernières années produit environ 16,3 kg de CO2 pour 100 km.

Et un humain alors ? Si on considère qu'une inspiration-expiration échange 0,5 L d'air, que l'air inspiré contient 21% d'O2, que l'air expiré en contient 16% et qu'on respire environ 20 fois par minute, on trouve qu'un homme produit 1,3 kg de CO2 par jour. Sachant qu'un homme peut marcher 40 km/j, il faut 2,5 jours pour parcourir 100 km, d'où une production de 3,3 kg de CO2/100 km. Sur cette distance, la voiture peut transporter 4 personnes sans produire considérablement plus de CO2, donc 4 personnes marchant 100 km produiront 13,2 kg de CO2, ce qui finalement n'est pas tellement moins (19%) que ma voiture.

La différence, évidemment, c'est que nos quatre marcheurs ne consomment pas de l'énergie fossile mais de la biomasse, donc le CO2 qu'ils produisent a déjà été extrait de l'atmosphère.
