rach,
actually, i think i shld hv wait to buy the 4.5L during sale time. tot i will b using it soon, so buy first to stand by.. in the end, i also only use it couple of times.... now too busi to cook or do anything with it.. lol
ya. cookin poridge with the 0.9L. i prefer thermos over tiger cos the tiger seems to b only able to warm instead of cook. but most likely is bcos i didnt preheat it n i cook less than half of the vol. thus not able to optimize it usage? one other mommy commented she preheat it, n it work fine. think is zenia, or another mommy? but i too lazi to go trial n error le... so juz use back the thermos. but thermos con is tat it easily spill out of the inner pot when shuttlin from my place to my mil (tat the main reason why i bought the tiger flask in hoppin to avoid tis.) cos need to bring alot of barang barang... cannot dedicate one hand especially for it la... hhahah
but recently i realise that using another method of boilin the porridge make it more soft for the grinded rice. it works sufficiently well for now. i didnt try this method back on the tiger flask though.. so duno if it can work there as well... =p
i bought the 6L n 0.9L 3 yrs back. serve me well. 6L come with 1 large pot or 2 3L pots. u can cook 1 3L pot by itself also. but it wont b as piping hot as using 2 boilin 3L pots at the same time. else, u can boil water using one (for drinkin), then the other one for soup. but i mainly use it to boil barley, sugar cane, apple, etc. cos mine is the shuttle series, i also put in cold dessert to ferry to my parents place for "party" of 6-8pax.
for the 0.9L, after my gal switch to eatin rice/ outside food. i use it to cook rice for the family instead. rice cooker kept away liao... can jux cook 0.5 cup of rice, also ok de. but if too little, at night when back from work ( i cook in the morning b4 goin to work), the rice b warm at most only. but if rice is at least half the vol of the pot, it will b hot.
for the 4.5L, i hv not use it tat often, so cant comment yet. but for the 2x i use, work effectively as the other 2 sizes. no big difference. =)
Duno if this lengthy help or not... lol
unless u wanan make some for me....]
