Cov pob kws tuaj yeem yaig vim ntau yam, tab sis lub ntsiab yog qhov tsis muaj fermentation. Yog tias, tom qab ob peb hnub tom qab cov zaub qaub, nws txoj haujlwm fermentation tsis pom, ces qhov no tuaj yeem ua rau lwj ntawm cov haujlwm.
Tsis yog txhua tus niam tsev ua tiav hauv fermenting zaub qhwv thawj zaug, vim hais tias nyob rau hauv kev txiav txim rau cov zaub kom tawm tiag tiag qab thiab tsis lwj hauv thawj hnub, nws yog qhov yuav tsum tau soj ntsuam ib tug xov tooj ntawm cov cai. Ua tsis tiav qhov tsawg kawg ntawm ib qho ntawm lawv tuaj yeem ua rau tshuab ntawm lub ntsej muag ua haujlwm.
Yog li, thiaj li yuav tsum kib zaub qhwv, uas yuav tsis qaub rau lub sij hawm ntev, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov zaub kom raug rau txoj kev fermentation. Cov zaub qhwv muaj ntau hom dawb nrog cov kua uas muaj kua thiab qab qab yog qhov zoo rau cov txheej txheem. Cov zaub ntsuab nrog cov nplooj ntsuab ntsuab tsis yog qhov kev xaiv zoo tshaj plaws, txij li lawv muab cov kua txiv tsawg kawg thaum fermented.
Ib qho tseem ceeb nthuav dav thaum fermenting yog kev xaiv ntawm ntsev. Tam sim no ntawm muag muaj ntsev nrog ntau cov tshuaj ntxiv, tab sis nws tsim nyog nco ntsoov tias thaum xaiv cov zaub qhwv, koj tuaj yeem ntxiv tsuas coarse pob zeb ntsev, uas tsis muaj ntau cov vitamins xws li iodine thiab lwm tus. Iodized ntsev tsis haum rau sourdough, yog li yog tias koj xav tau npaj cov khoom ua kom ntev ntev, tom qab ntawd tsis muaj qee qhov siv xws li lub caij ua haujlwm.
Kev ua raws li daim ntawv qhia kuj tseem ceeb. Ntau tus niam tsev, thaum pickling zaub qhwv, ntxiv me ntsis ntsev rau nws lossis tsoo cov zaub tsis zoo, yam uas tsis ua tiav cov kua txiv uas xav tau sib cais. Txhua qhov no tsis cuam tshuam txog cov keeb ua kom zoo tshaj plaws. Yog li no, yog tias qhov no yog thawj zaug koj txiav txim siab txog ferment zaub qhwv, noj ntsev tsawg kawg li 2% ntawm qhov hnyav ntawm zaub qhwv, tom qab ntawd txhuam nws nrog zaub kom cov kua txiv kom paub tseeb tias sawv tawm.
Zoo, nyob rau hauv xaus, nws yuav tsum tau hais tias zaub pob yuav ua lwj vim qhov tseeb tias nws "ua tsis taus pa". Thaum lub sij hawm fermentation, roj tau tsim nyob rau hauv cov zaub, thiab yog li nyob rau hauv tus ntawm cov roj cua no, yog tias lawv tsis tso tawm hauv lub sijhawm, lub workpiece pib ua kom tsis zoo. Yog li ntawd, kev tu ncua sij hawm ntawm zaub qhwv yog tib txoj kev tawm ntawm qhov xwm txheej no.
