1. Te Whakahāora Parauri
Kaupapa:
Whakawaikurahia te mata o te parahi mā te matū hei whakaputa i tētahi paparanga waikura (waikura kapu parauri), ka whakanui ake i te horahanga o te mata hei whakapakari i te kaha o te here.
Whakarongo:
1. Whai muri i te whakakōkō parauri, me utaina tonu te papa, ā, me whakakikorua. Ki te waiho mō te wā roa rawa, ka ngāwari ki te makuku, ka honoa ki te CO2 i te rangi hei hanga waikawa waro, ka whakarewa i te paparanga whakakōkō parauri, ka pā ki tōna kaha piri, ka piki ake te tūponotanga o te wehewehe.
2. Me tunu te papa he paparanga parahi matotoru (≥2oz) me te papa tahanga hei tango i te makuku nui.
Ngā tawhā tunu: 120℃±5℃×120 min
2. Te puranga o mua
Kaupapa:
E ai ki ngā tohutohu a MI, whakarārangihia te papa matua me te PP kia kotahi.
Hanganga noa o te papa paparanga 4
3. Te utaina o te papa
Kaupapa:
Whakatakotoria ia huinga papa kua whakarārangihia, kua whakapirihia hoki ki runga i te pereti maitai, kia rite ki te raupapa, ko te tikanga kia 4-6 papa hei hanga mō ia pereti.
4. Whakapiripiri
Kaupapa:
Mā te pāmahana me te pēhanga kua whakaritea, ka whakahaerehia te tukanga whakapakeketanga o te PP mai i te haurua-totoka ki te wai hei hono i te papa matua, te PP me te pepa parahi.
5. Te tango i te uta
Kaupapa:
Wetewetehia te papa whakakikoruatia ki roto i ngā PNL, ka whakamatao.
6. Te keri i te whāinga X-High
Kaupapa:
Hopukia te tūranga o te paparanga o roto o te ūnga whakairoiro mā te hihi-X o tePūrere hihi-X, kātahi ka keria ngā kōhao tūnga mā te keria ā-ringa.
