I always loved cooking- I just never had the time for it. I’d look up “20 min cooking” or “30-minute dinners” online, only for me to realize that it would take 1 – 2 hours because of prep time. Prep time includes cutting up the veggies, thawing the meat, and measuring everything. Forget the last part – I’m a Filipina and we don’t measure ingredients. Everything is “tancha lang” (approximating things).

Even good ol‘ Fried Chicken takes 40 mins to do.

  1. 20 mins to thaw chicken
  2. 3 mins to create a flour mix, put it in a plastic container with cover (so that all I have to do is shake it)
  3. 3 – 5 mins to heat oil to the proper temperature (deep fried)
  4. 15 mins to fry the chicken in batches of 3 pieces.

One of the reasons why I didn’t want buy slow cookers was because I thought it was expensive, both in price and cost in electricity. That was until I realized that my rice cooker consumes more electricity than the rice cooker I bought.

Kyowa KW-2800 Slow Cooker

  • 120 watts
  • 1.5 Liters

Standard SRG0 Rice Cooker

  • 350 watts
  • 0.6 Liters

Because I wanted to buy a slow cooker, I decided to learn how to compute its cost per hour. Based on Meralco’s website, the formula for this kind of appliance is Cost per hour = Rate x (appliance wattage / 1000). That sounded easy enough to compute. (Nosebleed moment)

To get my Rate I had to go to the site and check the table. My Kwh rate is Php 11.80 (because my electric bill is more than Php 7,000 a month).

To get my Appliance Wattage, I just checked the label below the cooker. In this case it is 120 Watts [see values above] and divide it by 1,000

Filling up the values:

Cost per hour = Rate x (appliance wattage / 1000)
Cost per hour = Php 11.80 x (120 / 1000)
Cost per hour = Php 11.80 x 0.120
Cost per hour = Php 1.40

If it takes me 8 hours to cook my dinner, that would just cost me: Php 11.30 worth of electricity.

Kyowa KW-2800 Slow Cooker

  • 120 watts, 1.5 Liters
  • Php 1.40 cost per hour

Standard SRG Rice Cooker

  • 350 watts, 0.6 Liters
  • Php 4.10 cost per hour

With that in mind, plus seeing how cheap it was to purchase online, I decided to just go for it… and received it in the mail a week later.

There was some beef tenderloin sitting in my freezer that wasn’t tender at all (no matter what I did – it was gummy, chewy, rubbery – you get it).


Just to test the cooker I did the following:

Ingredients

  • 1/5 kilo beef tenderloin, cut in strips
  • 1 cup cream of mushroom soup. I used Knorr
  • 1 onion, sliced

What I did:

  1. Sliced the onion.
  2. Dissolved the mushroom soup in a cup of water.
  3. Placed everything in the slow cooker and set it on automatic (4 hours high then automatically adjusts to low after).

Notes:

  1. I was truly surprised. I found out that if you used a cup of water or any liquid, it doesn’t evaporate or dry out no matter how long it sits there.
  2. The sauce became a gravy of sorts. I created mashed potatoes [failed] that ended up tasting good because of the gravy.
  3. It tasted better the day after when we had it with rice.
