A basic 1.040 starter is essentially a 10-1 ratio of DME to water.
If you have a 175ml vessel you can do 150grams of DME to 1500ml or water. Weigh out the DME and put it in the vessel and then fill to the 1500ml mark, shake to dissolve, boil for 10 minutes, cool to 70 and pitch yeast, shake vigorously and then periodically shake when you can or use a stir plate. Note, if vessel has a concave bottom a stir plate may not work with the magnet/stir bar.
I like to weigh the DME instead of measuring as since DME can pack down by weight is more accurate.
