• Nong (27°C+): Ty le 1:10:10 -> san sang trong 8-12 gio

O khi hau rat nong, dung 1:10:10 hoac tham chi 1:20:20 de lam cham moi thu va phu hop voi lich trinh cua ban.

Meo chuyen nghiep: Neu ban muon lam bot vao sang som, cho an truoc khi di ngu dung ty le cao hon.

Bay gio chung ta doi men chua cho thay hoat dong tot, dau hieu nam men va vi khuan dang thuc va len men.

Thoi gian dien hinh: 6-12 gio tuy thuoc vao nhiet do va ty le.

Men chua cua ban san sang khi no cho thay tat ca cac dau hieu chin, ma chung ta se kiem tra o buoc tiep theo.

Dung lo ve thoi gian chinh xac. Dau hieu cua men chua quan trong hon dong ho.

Dau hieu dau tien cua su san sang: hoat dong len men nhin thay.

Nhin men chua va kiem tra:

• Bong bong tren be mat? Lon hay nho, chung cho thay san xuat CO2
• Bong bong o hai ben? Kiem tra hai ben lo men chua
• No da tang kich thuoc chua? Bat ky su no nao cung tinh, ly tuong 50-100%

Nhung bong bong nay la CO2 do nam men va vi khuan san xuat. Nhieu bong bong = nhieu hoat dong vi sinh vat = banh mi no tot hon.

Dau hieu thu hai cua su san sang: mui dung.

Ngui men chua that tot. Men chua chin san sang nuong nen co mui:

• Giong sua chua (axit lactic, nhe va beo)
• Hoac hoi giong giam (axit acetic, chua nhung khong gay gat)
• Co the hoi mui ruou (san pham phu cua nam men)

Mui nen de chiu va can bang, giong nhu men chua chin “ngay truoc khi sup” nhu mo ta trong The Sourdough Framework.

Neu no co mui gay gat, giong nuoc rua mong tay (acetone), no da len men qua. Ban co the can can nhac cho an them lan nua.

Men chua chua cho thay hoat dong tot. Dieu nay binh thuong!

Cac lua chon:

1. Doi lau hon (them 2-4 gio) va kiem tra lai
2. Chuyen den noi am hon de tang toc

Thoi gian len men thay doi dua tren:

• Suc manh men chua (men chua moi cham hon)
• Loai bot (ngu coc nguyen cam len men nhanh hon)

Kien nhan! Dau hieu cua men chua quan trong hon bat ky lich trinh nao.

Mui cho manh moi quan trong:

Acetone/nuoc rua mong tay: Men chua da len men qua. Vi sinh vat da het thuc an va dang bi stress. Cho an lai voi 1:5:5 va doi 6-8 gio.

Rat chua/giam gay gat: Qua nhieu axit acetic. Dieu nay xay ra khi da qua lau tu khi cho an. Cho an lai.

Khong co mui: Len men chua thuc su bat dau. Doi lau hon, hoac chuyen den noi am hon.

Kho chiu/thoi: Neu men chua co mui thuc su te (khong chi chua), co gi do co the da sai. Bat dau lai voi lan cho an moi.

Hoan hao! Men chua cua ban dang cho thay hoat dong tot va san sang cho bot.

Ban da xac nhan:

• Bong bong va no nhin thay
• Huong thom giong sua chua hoac giam de chiu

Quan trong: Su dung men chua khi no dang hoat dong. Hoat dong vi sinh vat se bat dau giam khi chung het thuc an.

Neu ban khong the dung ngay, ban co the lam cham no bang cach cho vao tu lanh.

Tinh thoi gian nuong:

• Cho an truoc khi di ngu -> san sang vao sang
• Cho an vao sang -> san sang vao toi
• Dung ty le cao hon (1:10:10) de tri hoan su san sang

Luong men chua cho bot:
Hau het cong thuc yeu cau 10% men chua (50g cho 500g bot). Dieu chinh dua tren:

• Nhieu men chua hon (15-20%) = len men nhanh hon, co the len men qua nhanh hon
