Dnes sa naozaj c\u00edtime, akoby sme sa plavili morom \u201ebabi\u010dkin\u00fdch tajomstiev\u201c! Toto je jeden z najzn\u00e1mej\u0161\u00edch kuchynsk\u00fdch trikov, preto\u017ee napriek tomu, \u017ee je neuverite\u013ene jednoduch\u00fd, je zalo\u017een\u00fd na ve\u013emi konkr\u00e9tnom fyzik\u00e1lnom princ\u00edpe.<\/p>\n\n\n\n
Trik, na ktor\u00fd pravdepodobne odkazujete, je trik s drevenou ly\u017eicou.<\/p>\n\n\n\n
Trik s drevenou ly\u017eicou
Jednoducho polo\u017ete dreven\u00fa ly\u017eicu naprie\u010d otvoren\u00fdm hrncom, k\u00fdm sa voda (alebo cestoviny) vrie.<\/p>\n\n\n\n
Tu je d\u00f4vod, pre\u010do to funguje (bez m\u00e1gie):<\/p>\n\n\n\n
Preru\u0161enie povrchov\u00e9ho nap\u00e4tia: Bubliny vody s obsahom \u0161krobu (ktor\u00e9 vytv\u00e1raj\u00fa \u201ev\u00fdbu\u0161n\u00fa\u201c penu) s\u00fa nestabiln\u00e9. Ke\u010f sa dotkn\u00fa such\u00e9ho, drsn\u00e9ho povrchu dreva, okam\u017eite praskn\u00fa namiesto toho, aby sa hromadili.<\/p>\n\n\n\n
Teplotn\u00fd rozdiel: Drevo je izolant a zost\u00e1va ove\u013ea chladnej\u0161ie ako para. Ke\u010f sa hor\u00faca pena dotkne studenej ly\u017eice, para kondenzuje a vracia sa do kvapaln\u00e9ho stavu, \u010do sp\u00f4sob\u00ed, \u017ee bublina sa \u201evyf\u00fakne\u201c.<\/p>\n\n\n\n
\u010eal\u0161ie triky, ako sa vyhn\u00fa\u0165 katastrofe:
Ak nem\u00e1te po ruke dreven\u00fa vare\u0161ku, tu je nieko\u013eko rovnako \u00fa\u010dinn\u00fdch alternat\u00edv:<\/p>\n\n\n\n
Triky s \u013eadom: Ak vid\u00edte, \u017ee voda pretek\u00e1, ho\u010fte do hrnca kocku \u013eadu. T\u00fdm sa okam\u017eite zn\u00ed\u017ei teplota povrchovej vrstvy a zabr\u00e1ni sa st\u00fapaniu peny.
Kvapka oleja: Pridanie \u010dajovej ly\u017ei\u010dky oleja do vody s cestovinami pom\u00e1ha prelomi\u0165 povrchov\u00e9 nap\u00e4tie \u0161krobov\u00fdch bubl\u00edn a zabra\u0148uje im tvori\u0165 film, ktor\u00fd zachyt\u00e1va paru.
N\u00fadzov\u00fd \u201e\u00fader\u201c: Ak ste priamo pri tom, prudk\u00fd \u00fader na penu ju okam\u017eite vyf\u00fakne (ale je to len do\u010dasn\u00e9 rie\u0161enie!).
Slovo varovania
Triky s ly\u017eicou funguj\u00fa skvele, ale pam\u00e4tajte, \u017ee drevo sa m\u00f4\u017ee po\u0161kodi\u0165, ak ho nech\u00e1te hodiny nad hor\u00facou parou (mohlo by sa zdeformova\u0165 alebo praskn\u00fa\u0165). Pou\u017eite ju na t\u00fdch kritick\u00fdch 10 min\u00fat varenia cestov\u00edn!<\/p>\n\n\n\n
\u010casto sa v\u00e1m st\u00e1va, \u017ee voda pretek\u00e1 pri varen\u00ed nie\u010doho konkr\u00e9tneho, ako je ry\u017ea alebo celozrnn\u00e9 cestoviny, alebo ste len h\u013eadali potvrdenie tohto kulin\u00e1rskeho m\u00fdtu?<\/p>\n","protected":false},"excerpt":{"rendered":"
