\u201ePrepichnutie\u201c vaj\u00ed\u010dka je klasick\u00fd profesion\u00e1lny trik, ktor\u00fd z fyzik\u00e1lneho h\u013eadiska d\u00e1va dokonal\u00fd zmysel, aj ke\u010f sa na prv\u00fd poh\u013ead zd\u00e1 neintuit\u00edvne porani\u0165 vaj\u00ed\u010dko pred varen\u00edm.<\/p>\n\n\n\n
Tu je tajomstvo mal\u00e9ho otvoru:<\/p>\n\n\n\n
Pre\u010do je prepichnutie tak\u00e9 d\u00f4le\u017eit\u00e9
Prem\u00fd\u0161\u013eali ste niekedy nad t\u00fdm, pre\u010do maj\u00fa vaj\u00ed\u010dka natvrdo \u010dasto na jednom konci ploch\u00e9, preh\u013aben\u00e9 miesto? Je to kv\u00f4li vzduchovej kapse, ktor\u00e1 sa nach\u00e1dza na tupom konci vaj\u00ed\u010dka.<\/p>\n\n\n\n
Vyrovnanie tlaku: Hne\u010f ako vaj\u00ed\u010dko sk\u013azne do hor\u00facej vody, vzduch vo vn\u00fatri sa r\u00fdchlo roztiahne. Ak tento vzduch nem\u00f4\u017ee unikn\u00fa\u0165, tlak st\u00fapne nato\u013eko, \u017ee \u0161krupina praskne. Otvor funguje ako poistn\u00fd ventil.<\/p>\n\n\n\n
Dokonal\u00fd tvar: Prepichnutie vaj\u00ed\u010dka umo\u017e\u0148uje \u00faniku vzduchu a bielok m\u00f4\u017ee vyplni\u0165 priestor a\u017e po zakrivenie. V\u00fdsledkom je dokonale ov\u00e1lne vaj\u00ed\u010dko bez nevzh\u013eadnej prelia\u010diny.<\/p>\n\n\n\n
\u013dah\u0161ie \u0161\u00fapanie: N\u00e1zory sa na to l\u00ed\u0161ia, ale mnoh\u00ed kuch\u00e1ri prisahaj\u00fa, \u017ee medzi \u0161krupinu a membr\u00e1nu prenikne cez otvor mal\u00e9 mno\u017estvo vody. To pom\u00e1ha membr\u00e1ne \u013eah\u0161ie oddeli\u0165 sa od \u0161krupiny, ke\u010f sa vaj\u00ed\u010dko ochlad\u00ed v studenej vode.<\/p>\n\n\n\n
Ako to urobi\u0165 spr\u00e1vne (kontroln\u00fd zoznam pre odborn\u00edkov)<\/p>\n\n\n\n
Kde? V\u017edy prepichujte tup\u00fd koniec. Tam sa nach\u00e1dza vzduchov\u00e1 komora. \u0160picat\u00fd koniec obsahuje \u017e\u013atok a \u017eiadny vzduch \u2013 prepichnite tam a riskujete neporiadok.<\/p>\n\n\n\n
\u010c\u00edm? Ide\u00e1lny je \u0161peci\u00e1lny prepichova\u010d vajec, ale posta\u010d\u00ed aj jednoduch\u00fd, \u010dist\u00fd \u0161pendl\u00edk. Prepichnite len asi 2\u20133 mm hlboko.<\/p>\n\n\n\n
Kde? \u201e\u0160okov\u00fd\u201c moment: Pre dokonal\u00fa \u0161\u00fapate\u013enos\u0165 je d\u00f4le\u017eitej\u0161ie opl\u00e1chnu\u0165 vajcia po varen\u00ed v \u013eadovej vode ako ich prepichn\u00fa\u0165. N\u00e1hly pokles teploty sp\u00f4sob\u00ed, \u017ee sa bielok mierne stiahne a oddel\u00ed od \u0161krupiny.<\/p>\n\n\n\n
Mal\u00e1 \u201ekontrola m\u00fdtov\u201c:<\/p>\n\n\n\n
Veda n\u00e1m hovor\u00ed, \u017ee vek vajca m\u00e1 ove\u013ea v\u00e4\u010d\u0161\u00ed vplyv na \u0161\u00fapate\u013enos\u0165 ako prepichnutie. Ve\u013emi \u010derstv\u00e9 vajcia sa extr\u00e9mne \u0165a\u017eko \u0161\u00fapu, preto\u017ee membr\u00e1na je st\u00e1le pevne spojen\u00e1 so \u0161krupinou. Tak\u017ee, ak potrebujete vajcia do \u0161al\u00e1tu, je najlep\u0161ie pou\u017ei\u0165 tie, ktor\u00e9 boli nieko\u013eko dn\u00ed v chladni\u010dke!<\/p>\n\n\n\n
Vysk\u00fa\u0161ajte to nabud\u00face pri ra\u0148ajk\u00e1ch \u2013 prepichnite iba polovicu vajec a uvid\u00edte, \u010di pri \u0161\u00fapan\u00ed spozorujete rozdiel!<\/p>\n","protected":false},"excerpt":{"rendered":"
