Uyezve, kupararira kwakashanda zvakanaka mumabhatters ane chiyero chikuru chemafuta, kubudisa sarafu inonaka kwete zvisingatarisirwi kubva pakasashashi uye mafuta inoumba shanduko yewaini yakagadzirwa.
Mabasa ePotash uye Pearlash
Munyu weal alkaline, pearlash kana potassium carbonate (K 2 CO 3 ) inopinda nemvura kana asidi yakadai semukaka wakaoma, jisi rezvibereko, kana marlasses kugadzira carbon dioxide, iyo inopa zvinhu zvakabikwa zvinokwidziridzwa.
Baking soda (sodium bicarbonate) zvose asi inoshandisa iyo mumazuva ano mapepa emidziyo yezvakagadzirwa zveGermany. Shandisa 1/2 teaspoon yekubika soda yega yega teaspoon yeparlash inonzi mu recipe.
